Re: GA-P35-S3G overclock help please

Sounds good for sure for that board.

Ya, you should benchmark trfc 37-40 and see what performs best.

Memtest86+ passing that long but orthos failing ONLY means your CPU is at fault, so you need to adjust the volts to it, like a bit more. Or give up on that due to heat and back off a few Mhz

Re: GA-P35-S3G overclock help please

Yeah, I've been pluggin' some different numbers in. I really don't want to push this 3phase mobo much beyond 1.4v on the PWM, and that's what it'd take to get prime stable at 3gHz or more. So I've dropped down to 2.8gHz (8x350) and lowered the vCore to 1.35v, but I still need to stress-test it to see how much more juice it needs to be 100% golden.

At 350FSB, it has passed MemTest86+ without errors at DDR2-1050 555-15 at 2.1v using a 3x multiplier, and at DDR2-875 444-12 at 2.1v using a 2.5x multiplier. They perform about the same, but 1050 sounds more impressive than 875, so I'll stick with that, ha (for a day or two, anyway).

These are slightly lesser scores, but the CPU is using 0.0375v less juice.

My choices of 6-7-8-9 CPU Clock Ratio and all of the System Memory Multipliers allow for many possible setups. And I keep a spreadsheet that has it all calculated, which makes it easier to comprehend. I haven't dared to push this mobo much beyond 390 FSB, and I'm not too sure it can (can it?).

I spent all day at a Habitat house installing baseboard, so I haven't pulled the mobo yet. But after I re-TIM the NB and tighten my CPU HSF by shimming its backplate, perhaps it'll gain enough benefits to juice it up and try for 3gHz at 7x429 with DDR2-1030. In my dreams, that'd be nice. Have you got any idea how high FSB this P35-S3G can reach, stable? That little 50mm NB fan is the loudest thing in my box, and it might perform better on a taller HS.

Thanks.

Re: GA-P35-S3G overclock help please

That looks good, Tight timings as well.

Ya, you can go past 400 FSb no problem

I always redo the Paste under all heatsinks on my boards before I even fire them up. There is cement under there

I would say you can do 450 or so without issue

As for your NB, maybe you should get a ThermalTake Extreme Spirit II. I have used them in Several P35 and 965P builds and they work wonders and are pretty quiet at the same time. And less than $20 >>>>
Newegg.com - Thermaltake CL-C0034 Copper Fan & Heatsinks - Memory & Chipset Cooling

Maybe even cheaper if you check out ebay

Re: GA-P35-S3G overclock help please

I stopped Orthos-Blend after running for 13hrs-15min with 0 errors and 0 warnings.
(8x350 2.8gHz 1.35v ... DDR2-1050 +0.2v)

Temperatures from SpeedFan:
CPU ..... max-145.4 (62.9c) ... mean-143.6 (61.9c) / 135.5 (57.4c)
Core0 ... max-140.0 (59.9c) ... mean-138.2 (58.9c) / 131.9 (55.4c)
Core1 ... max-140.0 (59.9c) ... mean-138.2 (58.9c) / 131.9 (55.4c)

Voltages from SpeedFan:
CPU .... min-1.34 ... max-1.36 ... mean-1.34
MEM .... min-2.06 ... max-2.10 ... mean-2.08
+3.3v .. min-3.39 ... max-3.42 ... mean-3.41
+5v .... min-5.00 ... max-5.03 ... mean-5.02
+12v ... min-12.29 .. max-12.48 .. mean-12.30

The temperature mean fluctuates a lot, so I recorded the high/low that I've seen. Those temps seem acceptable at those speeds. I just kinda guesstamated the 1.35v setting in BIOS, so maybe it can be reduced a bit and still be golden.

Glad to hear that 7x429 is in the realm of possibilities on this board. It'd be interesting to see the effects of running the FSB that high, even if it were just for intermittent testing.

I'd read before that you'd recommended that NB HSF. It's a nice package. Both Newegg & eBay work for me, so I'll give it a closer look.

Thanks for invigorating these successful configs. Nothing's better for a geek than a helpful wizard.

Re: GA-P35-S3G overclock help please

Nice results. Cant comment on the temps, I am so used to seeing Celsius That makes me lost being in fahrenheit

Ya, it really is a nice cooler. Enzotech also makes a great NB heatsink, but you may have/want to get a 40MM fan to put on it. And those are hard to find quiet. But for $20 you can miss on that ThermalTake

Thanks for the kind words, and happy overclocking. Post back some results when you get into trying 400+ FBS. Dont get scared either, you can bounce in there anytime just to see how temps actually are anyway. A short boot into windows, or a few minutes of orthos to boost temps, to check wont hurt anything

Re: GA-P35-S3G overclock help please

This configuration uses the same voltages as above, but has faster CPU and MEM. The CPU reaches 151f-66c after an hour in Orthos, which keeps below the 158f-70c BIOS alarm. I also looped MemTests #5(x20), #2(x20), #7(x8) for a combined hour at 1083 with zero errors.

Re: GA-P35-S3G overclock help please

Looks good!

What are you seeing PWM temps with?

[jfk&g]

Re: GA-P35-S3G overclock help please

Temp3 in SpeedFan gives me CPU temps. The raw SpeedFan v4.35 is fairly accurate for this board. It correlates with temps & volts in PC Health in BIOS, and CPU-Z core volts. I simply use it for the readouts, no fan controls.

The booted Vcore is generally a little higher than the BIOS setting, but I've gotten used to it. For instance, at my current BIOS setting 1.35000v, my "drop" is 1.360, then it "droops" to 1.344 when I start Orthos. I get that three digit precision from CPU-Z, and SpeedFan reads it as 1.36/1.34 two digits.

I haven't tried the CoreTemp app that your sticky refers to. Suppose I should, eh.
... ... Got it. I like how I can set the interval to fractions of a second (500ms). Having it run beside SpeedFan shows that it's quick, but the readings generally agree with each other.

*BTW, if someone had told me this cheap RAM could run this fast, I wouldn't have believed them. I'm a believer now! It tested good at 1090 with the same timings.

Re: GA-P35-S3G overclock help please

Ill have to check it out then, I did test it not long ago and it just was not fully P45 ready yet. So that is why I asked about PWM, I really did not know a sensor was there for P35 or P45, maybe not for P45? I ran several P35 boards and everest Ultimate never gave out PWM temps for the P35's I have. And other brand boards that do have PWM Sensors show up in everest as PWM. So I just thought there is not PWM sensor on your board, but I could be wrong maybe.....

But I kinda doubt it, as that is the budget model and I have a DS4 and a DQ6 here and neither have a PWM sensor so I would assume you are looking at a "Ghost" value and just think maybe it is PWM. You should only see 3/4 one for NB/System (Will match Easytune) one for CPU and 1/2 for Cores. I do see how it could confuse you, I see PWM MANY Times on my Speedfan config screen, but NONE are PWM and 2 of the values are ghost values and can be deleted. As you can see here, it even shows "PWM" for CPU and cores as well, which we know is wrong. And dont get me started on tge voltages, but that is P45 only I think it is ok for P35 as far as those go >>>

Just want to let you know this, so you are not basing anything or planning to do anything because of a PWM Temp. I think that PWM it shows is for a PWM fan sensor is all, not a actual PWM/mosfet Controller chip.

As you can see in my image, using Thermistor (2C) or Diode(127C) for Both the Ghost settings You can see they are both VERY Wrong so it is likely just a incorrectly picked up or false/ghost reading and should be removed

But Hey, I could be wrong as well but I doubt it very much as my PWM's are not 2C or 127C for sure or I would see Ice or Fire

WOW that is strange to hear your Actual voltage is more in windows then what you set in the BIOS, are you using the latest BIOS? If not you should, as that is for sure a Error and should not be happening

Re: GA-P35-S3G overclock help please

Colors from your pic:
BLUE ... motherboard / NB[Temp1] ... same as my Temp1. I refer to it as the case temp. It begins a cold session at ambient temperature and increases over time by only by a few degrees, never spikes with a load.

RED ... CPU / CPU[Temp2] ... same as my Temp3. That's the one I refer to as the PWM. It spikes with a load, and is generally a few degrees warmer than Core0/Core1.

CYAN ... Core0/Core1 ... same as my Core0/Core1. They spikes with a load, work independently, and are generally a few degrees cooler than Temp3.

ORANGE ... Ghost ... same as my Temp2. It seems locked at 25f(-4c), and I've unchecked it from the front display.

I also display the SMART temps for HD0 and HD1.

I just assumed that my Temp3 (your Temp2) is PWM. Mine is only designated by SpeedFan as Temp3, not as PWM or as CPU. It derives from the IT8718F chip. It seems to react like the PWM sensors I'd seen on old 478 boards, but maybe I was wrong then, too. I don't understand why it would be named "CPU", since each core already has its own sensor, unless it's just referring to the CPU power circuit (Pulse Width Modulator, eh?).

Yeah, having a slightly higher effective core voltage than the BIOS setting is odd. It's like a negative drop, before the droop. But it has been consistent, so it's perfectly workable. My F4 BIOS was installed several weeks ago by Gigabyte, when I RMA'd this board for a corrupt @BIOS event. I've got no complaints. I can't seem to get it stable above 390FSB, but that can wait for another day.

[Lsdmeasap]

Re: GA-P35-S3G overclock help please

There is 3 sensors (DTS - Digital Temp Sensor) inside your CPU and all 3 give a different Output as you can see in my everest comparison.

So your Temp 2, that spikes with a load and is generally a few above the core temps is the actual CPU temp. So from what you say and what I know I believe I was correct and you have just confused this temp with your past boards sensor outputs, P35 does not show PWM/Mosfet temps.

Well at least you are aware of your voltage difference in the BIOS. I do see a beta BIOS available for your board, but depending on what caused you to RMA (@BIOS?) you may not want to flash to it. If you do decide to flash, please read the BIOS Flashing guide I pinned in this section

nope ... now it's getting Test#5 errors even with +0.2v MCH ... not done yet, ha.

[Lsdmeasap]

Re: GA-P35-S3G overclock help please

You should either raise static Tread, or raise your Ram voltage. Either way 5 may be too low to use at those ram speeds, and could be your only issue I see

[jfk&g]

Re: GA-P35-S3G overclock help please

OK. Thanks. It's still looping Test#5, and only erred in pass 9 of 43 passes, so it's real close. I'll let it keep running until it errs again. I don't want to raise the RAM voltage any higher, so I'll need to tweak the subtimings some more.

Just erred again in pass 51 ... reboot

Changed tRD=6, and keeping MCH=+0.2v ... looping Test#5
