Retail Q9650 Overclocking Thread

[Triton]

Basically I'm thinking of getting a Fermi card or 5870, then switching to the UD3P, and i might keep my current ram, or get something better. and try moving higher for a 24/7 clock on this thing. it works perfect for my now, I don't really need anything to much more.. but sometimes when I'm doing to much like encoding a Movie and playing Bad company 2, both CPU intensive I'll occasionally get a freeze, it's probably my 750i n oc.. I'd like to know it's 100% stable with a UD3P that will be much easier to achieve.

I had SLI GTX 260 + 750i SLI FTW... 3 of them...all broke their SATA PORTS. With voltmods, maybe 4GHz would have been 10hr P95 Stable...yes, did all the GTLVREF tweaking...gee

My tip: get any (well..UD3P ) decent crossfire P45 board and SLI hack it (google techpowerup forum sli hack, very easy, works great on W7 x64), use all your other current hardware: One thing is for sure, you will know CPU will run until anything else than mobo is limited. I know all about freezes on 750i

What you'll gain with SLI GTX260 on P45 vs NVIDIA mobo? Weekend's fun OCing the c**p out of your Q9650, 200MHz inc for sure. Gaming wise: more stability, higher fps

In a year or so, when your games run slow, put SLI GTX260 to 750i and sell for big bucks, buy ATI HD6850 2GB and keep UD3P....octacore in 2012 ?

for the ram: corsair 2x2GB 6400C5, this kit cost me sub 40€ last year...it'll run atleast 940MHz 5-5-5-18(i tested up to 4.2GHz, then bought 1150MHz ram - no gain), never tried higher. my advise is to not put moolah on new ram..save all for next gen GPU and hexa/octacore

Hi everyone !
Im going to get a 9650 or maybe a 9550, it depends on the price...
Anyway, I have a X48-DS5 and I would like to know if my processor will like it :P

I will sum the last 132 pages very easily. . .

Q9650 + Gigabyte EP45 UD3P or variants + GSkill PI's = dank

get rid of that X48 and enjoy stability at higher clocks

honestly I have been thinking about stripping everything out of the case, and using the motherboard box, or maybe even using this case and getting a triple 120. You think a triple would be necessary even if it was a single loop cooling only the cpu?

WOW very nice wprime run, 5 Ghz is very impressive

what is the VID of your chip?

I wouldnt mind getting a banchetto myself, there nice, right now im using just the motherboard tray from my tj07 as a bench station. Personally I would get atleast a triple rad, I started with a 220 and ended up adding a 320 later on since water temps with just the 220 were pretty warm. My vid is 1.15.

Nice time Hoss! So is that on phase then? I'm getting my EP45-Extreme either today or tomorrow, so I'll see how it fares on this chip. I'm going to try for a ~5GHz SPI run, but I fear my PI's limit will not take me beyond 1296 like I managed with the 1Gb reapers.
Do you get a big difference in times with 2x1gb vs 2x2gb?

No phase, im testing with dice for now. Its not necessarily the size of the ram thats going to affect the time but how they clock, and usually the 2x1gbs are just the better clockers, either with tight timings or high mhz. My Blades wont run 1300+ stably nor cas4 much past 1000 but the CSs will. Efficiency wise it seems the high mhz cas5 performs slightly better than the lower mhz cas4 but my board seems to prefer 1:1 over 5:6 after a certain point, around ~547-48fsb. If you have to end up running cas5 on 1:1 youll lose some time but I dont think it will be to major. Just try to keep it as cool as you can and go for that 5ghz run.

Very impressive for water, solid board too holding 560 FSB.

It was actually run on dice, my second time and was more of a testing/learning session than a max effort run. The highest I ran wprime on water was about 4965-70 for 32m and 4950 for 1024m.

Keep it going and try to tighten up those sub timings.

[l0ud_sil3nc3]

Keep it going and try to tighten up those sub timings.

which ones? PL level? tRFC?

I plan to get those down, I am pretty sure my GSkill's can do tRFC 52, I know 48 will freeze the entire system.

Am I missing anything here?

[Hoss331]

TRFC was part of it but the other sub timings look to be left on auto with the "Standard" memory profile. You can either change the memory profile to turbo and leave the sub timings on auto or leave standard as the memory profile but under Advanced Timing Control set the timings to 3-3-6-(52 or trfc of your choice)-3. Also when you preset the sub timings there is essentially no performance difference between the standard and turbo memory profile when using a 4GB kit, 2GB kit is a different story though.

I am running the Turbo profile on 2.50A. As soon as this prime test crashes (or finishes) I will double check.

[Hoss331]

Turbo or standard with timings preset would look similar to this.

[andressergio]

Insane CPU mate, nice work. Have to see what it can do on the new board when you get it all together.

thanks mate lets see and that was summer just water on the old setup can wait some benches on winter and new rad, block

go go mate !!! grats on that

[l0ud_sil3nc3]

so after 23 hours or prime small, as I was about to post a screen shot, I had a lockup. No BSOD, no error in prime, just a freeze as I was typing in firefox.

vcore maybe? or maybe more vtt?

[Hoss331]

It may be a nb/ram issue, post your template. Also dont bother running just small ffts go straight for blend.

lol why on earth u need 23 hours prime ? can be anything mate...any heat peak, any glitch on current...

blending as we speak


cpu vcore 1.35
cpu termination 1.32
cpu pll 1.57
cpu ref
dram voltage 2.08
dram termination auto
dram chA auto
dram chB auto
MCH voltage 1.40
MCH ref
MCH dram auto
ICH IO 1.50
ICH v 1.10

as for the refs I can't remember off the top of my head and I am priming now so I don't wanna reboot, but what I did was set vtt to 1.20 and then changed the cpu ref to 0.785 and the mch ref to 0.800 and then raised vtt back to 1.32v.

[Hoss331]

Just so you know the 1.32vtt setting does not work, it will stay at the 1.30 setting. When set in the bios it will still read 1.32 but actual voltage doesnt change at all over the 1.30 setting, 1.34 actually puts out what the 1.32 settings should. VTT up to 1.30 over volts a little and 1.34+ starts under volting by about 0.02. PLL also over volts pretty good so you can probably just use the 1.50 setting there.

Thats funny you mention the vtt under volting, I was looking at ET6 and noticed that my vtt read 1.30. I will change that and give it another try.

I usually do 8-12 hours depending, I just figured at such a low oc (470X9) it should be able to run prime for at least 24 hours.

[In-Fluence]

10 hours (i.e. enough for a complete loop of all FFT sizes in blend) is enough for me.
Still having a fair bit of trouble around the 480k/20k test area (around 4-5 hours into blend), with either hangs or rounding errors. I'm testing at 489x9/1.37v with memory at 1223 on 2.50a divider. It seems to like 1.28vtt the most, any lower and the board gets stuck at POST after a reboot, any higher, and blend fails sooner. MCH is at 1.54v and Tread is 8. Vdimm is set to 2.220v, although both do just as well with less. Have tried various voltages skews & ref changes, but still can't get through a complete error-free loop at this speed. CPU temps dont go beyond 65°C so I'm starting to suspect the board, but if anyone can offer any hints I'm all ears!

[Hoss331]

You shouldnt need anywhere near that kind of mch voltage for that oc, more likely the 1.40 area. Have you tried running it using 2.40B instead of 2.50A?

yes agree with you Cliff no way such MCH 1,4 will be good but he is using 2,50A wich is buggy and a hell on the MCH

[Hoss331]

I remember you having problems with 2.50A thats why I asked if hes tried using 2.40B instead. For one reason or other my board has no issues with 2.50A nor does it seem to need alot of extra voltage, 1.40mch for 4.5/1250. 2.40B on the other hand has always had issues with how much mch voltage it can handle at a given fsb before it will bsod or just not boot. Where your able to run 1.46+mch for 500x9 I cant go over 1.40 on 2.40B without have problems, 1.42 is kinda usable but 1.44+ will crash instantly or not boot at all. Theres a narrow usable window on how much mch voltage is needed to be stable yet not crash from having to much voltage and this scales with fsb, as it increases so can mch as it deceases so must mch or it becomes unstable. This is using the red slots, if I use the yellows the max usable mch voltage drops by about 0.02-0.04 (to about 1.36-38 at 500fsb).

Under 470 FSB it is very stable for me, however over that it is very buggy. 2.40B is always more stable at higher FSB.

yes i really dont have a problem just need lots of volts that dont justify for just 50mhz more...but remember that u have the blades...the gskill combo + that 2,50A diver is hard
