Re: My New Build

Well you can get stable now if you want, then work on a overclock once you get your cooler and then likely you will of course need to work on getting stable again after that of course.

This should be optimal for what you gave above, for 8GB

Re: My New Build

I agree. It's essential to have (imo) a default speed profile for a number of reasons including diagnosing crashes of software to eliminate an over clock as a source of issues etc.

After getting your 8GB stable (maybe) you'll have a better idea of what changes will be needed to re-stablise it at a higher CPU speed. It shouldn't be that difficult as you will merely be altering the RAM multiplier which will require minor tweaking. You need to concentrate on keeping the RAM running near stock speed, under never over IMO.

As soon as you have your cooler will be the time to crank it up a notch. Until then, stable is the objective at stock clocks. You can if you like then precede to push the CPU a little. You can OC on that cooler but probably not very far.

Re: My New Build

Bios Profiles:
Use them, you can save up to 8 different profiles. Use a profile naming convention that works for you. I suggest something like this:

24B333x800.5F+ (+ = stable setup, 5F => 5-5-5-15 memory timing)
26D333x888.4C? (? = bad and/or test setup and 4C = 4-4-4-12 memory timing)

I don't use the memory speed, as it is implied by the cpu frequency and the memory multiplier. My naming convention is:
494B20p9.52.5c+where:
494 = cpu host frequency
B20 = 2.0B system memory multiplier
p9 = Static rRead Value = 9 (A=10, B=11, etc.)
52 = tRFC
5c = 5-5-4-12 primary memory timings
+ = stable config

You can't delete an existing profile, but you can replace an existing profile later with different setup and just type over the old profile name with the new name. Flashing your bios will erase all your existing profiles. Make sure that you have a hard copy for each of your test scenarios, good and bad.

From the main bios screen:

F11: Save current bios settings
F12: Load a saved bios profile

Re: My New Build

Just to throw something your way....when you are having trouble stablizing this 8gig system with all 4 sticks, try bumping the voltage of DRAM @ 2.0v. I have had a similar issue where these chips are made to run at 1.8v but somehow using all 4 slots means not enough power being supplied to all 4 slots and/or unable to syn the memories.

G.Skill forums may have detail information on its safe voltage and product specs. but here is one of their response in specific to your G.Skill memories. Which I just pulled out of newegg's reviews under your ram specifics.

Manufacturer Response:.
Dear Customer

You may need to raise the memory voltage up to 2.0V to operate above 1000MHz. The actual memory voltage provided by the motherboard may be slightly too low which is why you may be having issues running at 1100MHz. Northbridge/MCH Core also needs to be raised to 1.4V in order to stabilize the memory controller.

Many motherboards can handle the full slots, it simply takes some configuring in your BIOS. We do warn people in our reviews, which is the main purpose for them. But like I said, by increasing the Northbridge voltage to 1.4V, it will stabilize the memory controller and as a result you should not have the "memory controller issue" anymore. If you have any further questions, please feel free to let us know.

Thank you

Any no no's that you guys can point out please do so but so far these settings are pretty stable, I checked memset and my ratio is 3:4. I'm hoping to achieve 1:1. I was reading up and it seems that the best way to achieve that would be to oc the cpu to 4.0Ghz and keep the ram at 800Mhz with a 4-4-4-12 timing as I was suggested. What do you guys think about that? Any better suggestions? Also I got a new cpu cooler. It is the Coolermaster V8. Would I be able to hit 4Ghz with this cooler? With the current settings I've got I idle at 34c and running linpack for an hour the highest it got was 62c. Please let me know what settings to change in order to get 1:1 ratio unless of course you have a better suggestion. Thanks again guys for your input and the help with this. Appreciated.

Re: My New Build

Well you seem to be moving on quite nicely :

Good cooler you bought there btw,and since mine came with i7 fittings ver a year ago,im sure yours did too
keep the fan speed adjuster turned up to the max,that will allow the fan to go to 2000rpm instead of the standard 1800 rpm under heavy load and it doesnt seem any louder at idle.
and it will cool a quad cpu at 4.0Ghz at least.

http://forums.tweaktown.com/f69/q8400-q8200-overclock-ep-45-ud3-high-fsb-37179/

I see youre on the mch v lower than standard ( which has been used before on the forum for 4 sticks of ram).

That doesnt work for me ,i run my mch more like the gskill response ( tho id never read that before).Still if it works for you thats all that matters.


If you want to overclock the cpu to 4.0ghz you cant run the ram at 800mhz.
445 cpu ref is as low as you can go with a 9x cpu multiplier for 4.0Ghz
that means the memory will have to run at 445x2 =890mhz as a minimum.

For information :In testing my gskill memory (800mhz) will hold 4-4-4-12 timings to 900mhz at 2.15V approx 920mhz at those timings needs over 2.2v in bios.

Holding the memory down at that speed,with those timings may give the best performance but If you are even considering a cpu speed higher than 4.0Ghz you may not be able to hold cas 4 timings.

It looks like you are down to a few considerations now.
1.you probably wont get a memory bandwidth higher than 9-10Gb/s (memory latency will vary a little)
2.try and get the cpu running as fast as you can with stability and holding 9-10gb/s memory bandwith.
3.Lsd has done some tests that seem to indicate D multiplier is better than B above 400mhz cpu ref.
4.In general you will want your memory running as fast as it will go ,but taking 1,2 and 3 above into account.

On the secondary memory timings static read or tRD provides the biggest difference for me (lower numbers are better).Its sometimes referred to pl or performance level.
I run with 9 which was harder to achieve than 10.
then there is the difference between turbo and standard memory settings.turbo improves the bandwidth by approx .5-.7Gb/s for me at high fsb.
You can adjust the settings manually,it does things like lower tRFC from mid 60's to early 50's etc.

I can see you going easily enough to 450 cpu ref
4.05Ghz cpu.. core voltage,id imagine you might need 1.32v cpu core in bios? maybe less.
The memory might be trickier ,using cas4 settings and 2:00D multiplier,I suspect you might need 2.1v+ in bios.
If you ease the timings out to 5-5-5-15 the mem voltage needed should drop a lot.
However if you go to 460+ cpu ref,920mhz + memory speed, your memory will start to perform better at cas 5 timings than it did at cas4 timings at 900mhz.

Nice on the xfire 5850's. The psu sounds plenty too but what are the amp ratings on each power supply bar .Are u overclocking the gx cards also.

If i had a 9650 to slot in id be going for the 4.5Ghz.."just cos its there" but even then id be expecting less of a noticable performance improvement than I got when changing from a 3.5ghz to a 4ghz cpu( l2 cache amount doesnt make that much diff in real terms)and even then the performance jump wasnt anything like bringing my 2.3ghz cpu to 3.5ghz.

You are already running faster than my old cpu was ."pedal to the stability metal" ,at stock and even below stock voltages.

Nice speeds and probably temps too,and you still have a lot of headroom. If you do get near 2000fsb you will probably need some higher voltages,whether its worth it to you or not,cant say.
