How can I improve my Q6600 OC? - Page 2

post #11 of 19
Thread Starter 
Thanks for the feedback people!

I will try going to the x8 multiplier, see how far I can go.
Thanks for the suggestion of getting abetter memory, if you look in my sig I alweays had the memory you just bought... ;-)

I don't think temps are the problem just yet, I'm avaragign 65c under full load and I understand with the Q6600 as long as it bellow 70c it ok, I also believe I have more headroom on the voltages, my case has got excellet (if noisy) air cooling.

I will consider lapping m,y cpu cooler but don't think I have the political clout to spend on the system for the next coupel of months (i.e. the wife won't let me ;-)

If I do aim to go for 500x8 what voltages should I increase etc?

Thanks!

people thanks for the advice.
I will try the 'x8' route, let's see how far I can get.

Thanks for the advice about the memory, if you notice I already have the memory you recomended... ;-)

I don't think the temps are too high, I;m gettign 65c under Prime load and in gaming it never goes above 60c, my understanding is that you shouldn't go above 70c...

I probbaly can't spend any more of the system for the next xouple of months (the wife won't let me) but I will l;app it and reseat it at some point.

If I am going for 500x8 - which voltages should I increase etc (please see attached)?

Please share your thoughts,

Thanks!

Don't go 4.0 gHz without water cooling. That being said 3.4 - 3.6 is very acheivable with a TRUE cooler.

I can push the FSB to 420but Vista crashes in a minute. I suspect the reason is my memory settings - which I havce no real clue about. Please share your thoughts on how to improve this.
What are the stock memory timings? Find out the numbers from the OEM and stick as close to those as possible.

My VID sucks, 1.325. But I did get the G0 stepping one. Not sure if his is the same as mine. This quad is only 2 weeks new. No problems though on the OC, the only thing holding me back is the crap cooler. I should really have invested in a TRUE then I would totally go 3.4.

you'll NEVER get a 100% 24/7 stable 4G on air. and you'll never achieve it at 65c . for low to moderate OCing 65 is fine but not for top end stuff.

Hi People,

Some replies:

My CPU is G0 stepping with a 1.2750v vid - so I guess it's on the low end?

I did manage to boot into windows at 475x8 (3.8Ghz), but Prime (and vista along with it) crash instantly. I feel I should perhaps add some voltages somewhere or perhaps somethign else, please share your thoughts.

Regarding the memory timings, here is a very good review of my memory, it can clearly go fairly high - I need to work them properly.

3.6GHz (1.376v Vcore) is really rock solid on my system, I've been gaming all week without a hitch, 4Ghz is a little over 10% and I'd like to give it a serious try - please advise,

Thanks!

You should be using default values for all of these..increasing these values should be reserved for extreme FSB OC's only, as they will provide only a small increase in stability then. Using them at lower FSB's has no effect that is beneficial.

*For 475mhz FSB you will need to increase your PLLv, MCHv and GTLv [unless at the same CPU clock with lowered mutli]

I couldnt help but notice you had some settings in your first post, that could be affecting the stability of your system..and killing your bandwidth for memory.

Quote:
Performance Enhance...................: [STANDARD]
Extreme Memory Profile (X.M.P.).....: Disabled
(G)MCH Frequency Latch...............: [Auto]
System Memory Multiplier ..............: 2.40B
Memory Frequency (Mhz) ..............: 1066 960
DRAM Timing Selectable ................: [Manual]
Bump your MCHv a notch and set:

Performance Enhance...................: [Extreme] Use higher MCHv values for decreased latency settings.
(G)MCH Frequency Latch...............: [333mhz] <- set this to match the divider strap..

ie- 'B' dividers are the 333mhz strap dividers..so any 'B' divider entered = MCH Latch @ 333mhz . A = 200mhz, C = 266mhz and D = 400mhz, for all mem dividers in BIOS

Static tRead Value.........................: 9 [<- very important latency change..and crucial to stability. Heavily tied to MCHv setting] Use higher MCHv values for decreased latency settings.

MCH Reference ……………………… …………… .......: [x.65] [boosting this value will increase the default core voltages for the MCH..and can be very helpful, with lowering the amount of MCHv set as well.] Use higher values for decreased latency settings.

I say raise your MCH to 1.4 and your PLL to 1.6 or so.

Get a better CPU cooler and bump it up to 1.5 vcore if you get to close to 70c on load then try lapping your cpu and heatsink. If you do the lapping procedure correctly you should drop up to 10 degrees Celsius. I wouldn't try to go much farther than 4000mhz.

Thanks for the great ideas!

I'll be back at my computer in the weekend, and will try them out!

Will report back, thanks again!
