$200 or $240 for GTX 970 performance is a game changer!
Current GTX 970 prices at Newegg are $270 - $350, quite a few models are in the $400 - $500+ range and one model sells for $650!!

Power Consumption Concerns on the Radeon RX 480 - PCPer

From the PCPer article:

UPDATE 2 (7/2/16): We have an official statement from AMD this morning.

As you know, we continuously tune our GPUs in order to maximize their performance within their given power envelopes and the speed of the memory interface, which in this case is an unprecedented 8Gbps for GDDR5. Recently, we identified select scenarios where the tuning of some RX 480 boards was not optimal. Fortunately, we can adjust the GPU's tuning via software in order to resolve this issue. We are already testing a driver that implements a fix, and we will provide an update to the community on our progress on Tuesday (July 5, 2016).

Memory arrived early! and its Looking good so far, not sure if I'm running the right test though :D


I've also got no experience with playing around with memory timings.


Should I change the timings? Because in memtest I see CAS 6-7-7-19. Which is different to the sticker on the mems as you can see in the attached pics.

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Your memory is rated for 5-4-4 primary memory timings with DRAM Voltage = 2.10 volts
The pre-programed timings are 6-6-6-18 at 1.80 volts with the bus speed set to 400MHz.

Memtest86+ errors indicate hardware problems or bios settings that are not "close enough."

Set the primary timings to 5-4-4-15 with DRAM Voltage = +0.30 which will set the voltage to 1.80 + 0.30 = 2.10 volts.
Set (G)MCH OverVoltage Control = +0.1 or possibly +0.2, there will be boot problems when this is not set correctly.

Memtest86+ is good for an initial memory test but you will be using Prime95 to torture test your memory each time you make any bios changes. If you are not familiar with Prime95, click on the Prime95 tutorial link in my signature. I suggest running each test for at least 8 hours, but you should stop the test at the first sign of any errors. The Prime95 Large FFT test is best for stressing the memory, but the Small FFT and Blend tests should also be run, one at a time.

I run a brief 15 minute LinX test before I run Prime95 tests. LinX (and IntelBurn Test) are not as thorough as Prime95, but if there is an error with LinX or IBT, your system is not stable and it's a waste of time to then run a long Prime95 test. I run with 3072 or 4096MB of memory using 4 or 5 test loops. Cpu core temperatures will be about 10^O C higher than Prime95.

Post a detailed screenshot that includes:
Cpu-z, Cpu window
Memset v4.1 showing the main window and it's SPD window, press the ">>" icon to display both memory channels and SPD to display the SPD screen.

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Hello guys. I have a P5Q Deluxe board with a X5460.
I managed to clock it to 4ghz by just setting fsp and vcore(1.26v).
I am trying to get some better clocks from it, but i cant.
I bumped my FSB to 440 and my voltage to 1.29v. After setting my FSB voltage to 1.20 , my northbridge voltage to 1.2 and my southbridge to 1.14, i managed to boot in windows. About 10 seconds of prime95 running will give me a bsod with an error like whea uncorrectable error.
I bumped FSB to 1.3, northbridge to 1.24 and southbridge to 1.2, but i still get the same error. I also bumped my ram voltage to 2.1v
Still nothing. Am i missing something?

ps. i forgot to say that i also bumped my vcore to 1.3, with no success.
ps2. my ram is just random brands. two are kingstone hyperX 800mhz, one is apacer 800mhz, and the last is mushkin 667mhz. can this be because of my random ram?

Thanks in advance!

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Welcome to the forum.

Using mixed memory modules often causes problems, especially when using four memory modules.

You haven't provided detailed information about all of your hardware and you haven't included a bios template that shows all of the bios settings that you are using. We also don't know how good your cpu cooling setup is or if the cpu core temperatures are too high.

The best thing that you can do is a web search using: p5q xeon overclock and find a thread that is dedicated to similar Asus P5Q Xeon setups.

Also check out ASUS P5Q-E and Xeon X5450 Overclocking

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Hello, and thanks for the reply man!
I did not mention my cooling system because its not a problem(atleast on 4ghz). I have a raijintek themis evo. My idle temps are about 26-27C, and the max i ever saw, was 51C. When stress testing with prime95 of course. (You guessed it. its a E0 chip)
I did not make the custom bios. A friend did it back when i bought the xeon. But its for sure modded to support the Xeon, and also the latest one.
I also thought that memory could the issue. I will try same settings, when using only the two kingstone dimms, which are a set.
Thanks again!

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Hi folks, I hope someone can give me a little direction here as I haven't come across anything like this online, so bear with me a bit here:I have an old GA-P35-DS3L v2 board (with 771 socket mod and a [email protected]) and had been trying to overclock it recently w/o success. Like at all. Couldn't bump up the FSB mhz or voltage w/o BSODing. I may be able to get it to run at 3.4ghz, but I'm sure if I left Prime95 running for long enough, it'd BSOD eventually. Fine, but I was curious as to why as many others have been able to get great overclocks and not me.
So i reset all the BIOS settings and then I finally paid some attention to the readings from the various sensor apps (HWmonitor, CPUz, BIOS readings, etc) and started to notice something odd.
(remember these are stock BIOS settings)
- CPU Core temps seem a bit high for idle temps. I'm idling at 49C-50C. But I might be confusing core temps and CPU temps.
- CPU voltage SHOULD be at 1.2375, however they barely hit 1.2 and usually stay around 1.184 - this seems not ideal. Reading in various forums, it's expected to have slight drops here and there but nothing like this where I'm never even hitting the stock settings.
In an effort to stabilize it all, I took all the BIOS settings off auto and manually fixed all the stock settings (so I know the BIOS is telling the computer to be running at those stock settings). The settings stick, however the BIOS has it's own monitoring screen and it shows the voltages still not hitting the stock value of 1.2375, though the temps are a bit better @ ~39C. Another thing to note is that no matter how high a voltage I set, it never reaches it. I think the highest I was able to get it to report was v1.28 and I had it set at 1.35 or somewhere in that territory (and cores were hitting 70+C)

So, looking at HWMonitor, you'll notice that the values are fluctuating a bit. They really shouldn't be as I've manually set them all in the BIOS and disabled all settings that limit the CPU (speedstep, etc)
other things to note:
When trying to overclock, raising the voltage seems to make the system unstable faster than raising the fsb (tried this for 'fun')
The CPU cooler is newish (about a year) and is a Deepcool Gammax 400
I've tried both 1066 (7-7-7-18) and 800 (6-6-6-12) RAM
The PSU is 7-8 years old and is an OCZ 600W PSU with 80+ something rating, blah blah blah. Either way, the voltages reported by HWmonitor seem 'OK' to my untrained eye and even with some degradation is wattage, there should be plenty to supply my system.
So, do I have voltage problem with my CPU, motherboard or PSU? what's the most likely cause here?

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Welcome to the forum.

We don't know which bios version you are using.
Has the Xeon X5460 bios mod been applied to your bios? If the answer is NO, do a web search using: X5460 bios mod P35-ds3l

The first 1/3 of this thread deals with Luke's Xeon/P35-DS3L and my suggestions.

Even though the reported voltages look good, an old psu might not supply stable voltages.

The bios shows 1.888 volts for your memory but this might be too low, depending on how much memory you are using.
The MCH Core voltage setting in the bios that is set too high or too low can cause boot problems and/or system instability.

You will see in this thread that Luke and I provide very detailed screen-shots that provide a lot of information.
You should always provide an accurate updated bios template every time you make bios changes along with a detailed screen shot.

System software will probably report higher than normal cpu temperatures because the software is using TJ max = 100, while your X5460 has a TJ max setting = 85. This doesn't affect your real world cpu temperatures, but the software will report temperatures that are 15⁰(C) higher than normal with your Xeon cpu.

We need detailed information about ALL OF THE HARDWARE in your system.

We can best help you after you create a detailed hardware list in the System Specs
portion of your forum profile at the bottom of the profile page or in your forum signature.
Be sure to include brand names and model numbers.
When you are done editing or creating your hardware list, save the settings.

I can't help you further until you have provided a detailed hardware list in your PC Specs.

[SlugMan]

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Thanks for the reply.
I've updated my specs in the my profile. Is there anything else I'm missing?
Also, yes I forgot to mention my BIOS. It was originally given to me by the person i bought the x5460 from. But then I wanted to rule it out so I recreated my own F9 bios + 771 microcodes and reflashed only to have the same results.
The RAM should be at v1.8 according the spec sheet for both 800 and 1066 modules I have. I have tried upping the RAM voltage to no change. Not sure why it's reporting voltage? I was thinking of hopping into MEMTEST86 to see what it'd say.
I have scoured this thread, and others, to try and overclock my hardware. But I just don't get very far.
1 - After manually setting stock values (as shown in the above screenshots) i begin by upping the FSB in 100mhz increments. 333 -> 342 -> etc until I get my first error/bsod as reported by Prime95
2 - increase CPU voltage and drop FSB by 50mhz. It may last longer but eventually there still will be errors/bsod. try upping more CPU voltage some more. bsods become more frequent and eventually the computer doesn't bother showing them and just restarts.
3 - attempt moving up other voltages to gain stability (mch, ram voltage, fsb voltage, each one by one with tests in between).
with CPU temps hitting 70C and CPU voltages still nowhere near what I've set in the BIOS - in fact, and it may just my imagination, the gap between what I set and the highest reported voltage seems to increase, but i have no hard data on that. and I think the string of BSODs i received have ended up corrupting some Windows Update files that I can't repair (but that's another problem).

..and I'm lucky if I get to 3.4ghz before the sh*t hits the fan.


You don't seem concerned about my CPU voltage. any reason? All the other overclocked CPUz screenshots show voltages to be what was manually set in the BIOS. But mine do not (including on the PC Health Status BIOS screen).
I have limited information on this, but the other voltages as I've seen in other folks HWMonitor screenshots show similar numbers for 12V, 5V and 3.3V. If my PSU was failing, shouldn't there either be a) higher fluctuations b) lower values. I have contemplated getting a PSU tester to be sure. But I'm running out of excuses to keep spending money on this aging machine.

oh, and the X5460 is C0 version, if that makes a difference.

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

I wonder if there is a problem with your bios microcode mod.
I haven't personally used Xeon processors so I don't know how to check if the microcode mod is good or bad.

The first thing you should do is load optimized bios defaults, save settings and exit the bios, then reenter the bios if you want to make any bios changes.

If you haven't done so yet, test your system at stock speeds by running Prime95 for 3 hours, three times. Run the Prime95 Blend, small FFT and large FFT tests separately for three hours and stop if one of the Prime95 worker threads has an error. If your system has no errors after all three tests have completed, your system is somewhat stable. There's no sense trying to overclock if your system isn't stable at stock speeds. For me, a system is reasonably or mostly stable if each of the three Prime95 tests run for at least 8 hours.

This is a long shot, for now, try running with a 2 x 2GB instead of your 4 x 2GB setup.

I'll be back in about 7 hours and will check back on your progress.

Provide detailed information, such as the BSOD error code, for example 0x124.

Create a single screen-shot with the following Cpu-z windows: CPU, Mainboard, Memory and SPD.
Memset v4.1 provides more detailed memory information.

I've found that Memset86+ is more reliable than the older, original Memset86 program.

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

I followed the directions here:
How to Update CPU Microcode in Award or Phoenix BIOS - For LGA 771 & 775
to create the BIOS I was originally given. There's a tool to check to see if the microcodes you need for your CPU are present and it seems to check out.
I'll run Prime95 running over the next few days doing the tests you suggested. I've run it overnight a couple times when I returned back to 'manual-stock-settings'. Seemed to check out fine for an ~8 hour run, but I could be more thorough so I'll do that.
I ran Memtest real quick, mostly to see what timings it reported for my RAM. looks fine there. I'll run that also for a few hours.
here is a snapshot from 'BSOD-Viewer' to give you an idea of what BSODs I encountered during my last attempts at OC'ing: I'll post new ones as they happen and let me know if any of the following need more info.

and CPUZ

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Just a quick update:
I've run Mmntest86+ 5.01 for 8 long passes on the 800mhz modules. I was going to put the 1066 Crucial sticks back in, but: a) it's sweater season, static everywhere. b) They're a bit of an 'unknown' in terms of brand and I wanted to really tests them while I had them in.
So after the 8 passes, they seem to check out fine. No errors reported.

other notes
I have not reset the BIOS to stock/factory values. Still on the forced/manual stock settings I put it on.
I'm about to leave Prime86 running for.. a long time. hopefully more than 8 hours.

Happy Holidays everyone!
Don't let my silly problems distract you from any Holiday activities if you're participating!

[SlugMan]

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

another quick update:
Prime95 - Blend Test - ran for a little more than 12 hours w/o incident.
same bios settings and 800mhz RAM modules as mentioned in the previous post.

I'll start one of the FFT tests and let it run overnight.

curious HWMonitor readings. I've read that underload, CPU voltage does/can drop and it seems it dropped to the lowest value i've yet seen. Same goes for CPU clock speed. Remember, the BIOS settings should be forcing more stable voltage/clock speeds.... and probably also why I should be testing with 'optimized bios settings'
