in order to get this i had to run up a vtt of 1.46 and pll of 1.57, think i should back it down????? cause i already have been able to lower the cpu vcore from 1.44 down to 1.40 for 1.37 in Windows with the droop?????

i just want this cpu to last more than a few months.... that's al..

Thanks folks

Enable Load Line and that will cure some droop, unless you already have done that then cool. I think what voltages you have to use depends on the chipset fate dealt you. In other words if that is what it takes to keep it stable then stay at those settings.

You just have to keep everything cool and you will be fine. Check my post with my settings for 4.2GHz, I'm running this 24/7 have been for awhile now..

[Gameman]

speaking of which, i just did a little minor tweaking and got 4.2 ghz stable so far, although photobucket and firefox crashed once - maynot be related but there you go.....

no bluescreens yet, just that first time when i forgot all about vtt

although this is a bit high, i personaly wouldn't run it at this around the clock, just for benchmarking, 4.0 is fine

you are very polite, thank you highroller..i will check your settings in a little bit... but jeez this is a good board - i cold never dream of 525 on a Quad on the other one..

edit, oh sorry for the double post, i thought it would have merged it....oops

[In-Fluence]

The multi is not the issue, its the cpu speed, the higher you go the more sensitive it becomes to core temps. The 8.5 only gives you 4.25ghz so its obviously going to be far easier to pass than 4.5 and be less sensitive to the heat.

I totally see where you're coming from. After a bit of a cleanup, and mounting the original heatsinks (except NB) and I've had a little more success, but I'm still fighting with temps, and can't really keep any lower than 71°C on the first core... the other three are about 6°C lower, with the 4th core (which runs at the 3rd lowest temp) being the weakest. 0.785 CPU ref (with 1.36vtt) seems to give me the best results, but at 0.760 the 4th core then becomes more stable, but the 1st and 3rd fail quicker. Changing vtt up or down a few notches and testing higheror lower refs also didn't seem to help much.

I reckon I've probably scorched this chip a bit, although it's own temps were reasonable, and rarely got into majorly dangerous zones, I did run very high pll & vtt a couple of times for benching/max fsb and CPU speed. Getting it stable at this speed is definitely not as easy as before. I've stuck with 1000/1000/0/50 in the drive/skew section, but I'm getting quite a few BSODs on shutdown, and sometimes within 2 minutes of booting as well...One of my HDDs are old so it may need replacing.

I'll post up my previously stable settings at 500x9, and wil be open to further advice, but I'm not holding a lot of hope in getting it back to the way it was and might have to back down to something like 4.4 now I guess that's still half-decent.

[RAMMAN]

anyone here tried 266 strap 2:3? because im finding even 400 strap 3:4 isnt enough to push my memory, or maybe i just need more than 1.24 mch voltage to get more than 468fsb 1248 memory speed lol.

edit: unfortunately there is no 2:3 on the 400 strap for my board, just 1:1, 3:4 and 3:5

mate i would for more MCH i use 1,46 24/7 for my 1200 Gskills PI and Q9650@ 4500

maybe 1,3ish

Cheers and have a good 2010

no mate wont harm

im a year now on this settings still passing same tests...and also a vid 1,1875

[RAMMAN]

im just a little cautious with mch voltage because my last board(ga-p35-ds3p)somehow degraded very quickly with +0.2v mch, went from being capable of 1280 memory speed to incapable of 1000 in a matter of minutes. freak accident, temps or p35 chipset cant handle as much volts? i think the default mch voltage for that board was 1.2 while my current board definitaly defaults to 1.1v. anyone able to to do performance level 6 beyond 400fsb? im thinking of trying some benching with really tight timings, 8x425fsb 1133 4-4-4-12 pl6 200 strap 3:4. apparently defaults to pl6 at 333 fsb 200 strap 3:4 4-4-4-12 so just have to raise mch to 1.3v dram to 2.35 or 2.4v and just raise the fsb with setfsb correct? higher vtt than default 1.2 shouldnt be required at 425 fsb. i would use easytune6 but it raises fsb 11 at a time :/

[OC Nub]

If you put a good fan blowing on your nb you should have no problems. I ran 1.46v MCH with my q9650 for months, using the same exact settings Sergio is using. I took the blue gigabyte cover off and had a fan blowing on the nb hs.

[Hoss331]

Finally got my nb block switched over to this board and went back through my 4.5 settings to settle on these, for now.

[kagula323]

Great overclock Hoss331. What DDR3 kit are u using?

[In-Fluence]

Damn, those EP45T's really seem to play along nicely with quads too Hoss331, and that vcore is astounding! If I knew a little sooner I would have probably gone for one of these and avoided all the hassle I've had with getting a decent set of DDR2. Since mid-november I've been waiting on nearly £200 worth of refunds from a DOA kit and a pair of mislabelled dominator GTs

I backed down to 490x9 last night and CPU was stable with 1.40625 vcore (1.36 in CPU-z), so whatever damage I might have done, it doesn't seem too drastic. Just nudging up to 495x9 now, and I'm getting errors about 12 minutes into small ffts which I think is a good point to properly tune the refs and vtt as I've not been 100% on these.
I've gone about finding stability using my knowledge from the MIIF, which has got me a fair bit of success, but I would like to hear a summary of some of your methods in case I'm missing anything if anyone is willing to oblige?

[humeyboy]

So your GT's were not really GT's ?


http://www.overclockers.co.uk/showpr...d=8&subcat=817


Corsair are stupid (after my RMA anyhow), they shouldn't have made the GT's 1066 but 1200 at least, just as stupid as that new fast Voyager GT that claim is only bottlenecked by USB2.0, so why the hell not make it USB 3.0 now or wait a while.

andre, could you post up your template please?

Thanks

[In-Fluence]

No, I assume they were, but they were labelled 1.65v and scan had them rated at 2.1v. There's no info on Corsair's site but on their forums they stated 2.1v too. At the time, my MIIF vDimm only went as low as 1.8v and at 2.1v they threw out tons of errors. For a £120 4GB kit I expected a lot more performance and suport, particularly as these were supposed to be their 'flagship' category, but that appeared to only apply to the DDR3 range. Once again, I wa suckered in by the fancy looks & packaging. They might perform a lot better on this board, but I never got the chance, mind you, as I'm still waiting for a refund, I'm tempted to ask for the kit back to see if lower volts help more..
Here was what I reported on them at the time...
http://www.xtremesystems.org/forums/...ight=dominator

I've just been testing how much mch I need for 495x9 and I'm down to 1.24v (and testing at 1.22). Once I went below 1.26v I had to raise MCH ref to 0.84 (using ET6) to pass 1024k fft. I know there's more testing needed, but it's helped me tune & learn a little more, plus it won't hurt temps!

[maxwedge]

I've been thinking of trying out a GA45T-UD3P and some ddr3 but hardly anyone is stocking them. You think Gigabyte may be coming out with a new revision or just dumping it?

I found a few v1.0 on ebay but if their going to put out a new one I should wait.

[Don_Dan]

Could someone please have a look over my settings and give me a hint what to change, I must be missing something. I had 510MHz x9 stable enough for benching all day, I increased some voltages and went straight to 530MHz x9. I could enter Windows once but it crashed while running Aquamark, afterwards I could no longer boot these settings and had to clear CMOS. I entered all my previous settings for 510MHz FSB, at least I thought I did, but they didn't work anymore.

Just for your info, I have lots of fans and ambient temp was ~0°C.
CPU is my E8600, I'm running BIOS F9I on my UD3P.

Please help me, this is quite frustrating.

[OC Nub]

Just wondering if you normally used 700/700/0/0 for your advanced clock control? Your CPU and MCH ref's look low, are those the settings you used with default VTT-1.20v before raising it to 1.4ov? With my e8400 if I remember correctly, the MCH ref need to be a notch or 2 lower than the CPU ref for 4500mhz stable.

Yeah, 700/700/0/0 worked fine until 460MHz, and 510MHz worked well too. I looked at some other settings posted in this thread, looks like most people use 800/800/0/50 or even higher skews plus higher refs, I will try that tomorrow.
Anything else that comes to mind?

[OC Nub]

Thats all I saw, that and the ram voltage is higher than I have ever used lol. Everything else looks fine to me. I used Auto for some of the other ref's but if Normal worked for you before it shouldn't be a problem now. Radaja is good with the c2d settings, maybe he will have some better idea.

Have you tried using PL8-240B? It worked fine with the G.Skill PI's well over 1200mhz.

[RAMMAN]

whats the best divider and strap for 650mhz+ on the memory while still keeping high fsb? im thinking 3:4 400 strap as if i manage 500 fsb that would mean 666mhz on the memory. 3:4 200 strap drops my max fsb by 20-30.
is 500fsb 666mhz memory a realistic goal or should i try 2:3 266 strap to get 650mhz+ on the memory? unfortunately 266 strap is the only one that has 2:3 divider on my board, 400 strap has 3:5 instead
