Overclocking help

The IPB · 10 Dec 2007 at 07:37

Just started overclocking for the first time an need some advice.

Firstly rig =
Q6600 + Arctic Freezer
Abit IP35
4x1gb Geil PC2-6400C4 800MHz

I have slowly been upping the fsb, which is now 333 with a multi of 9, am I right in thinking this is now 3gig? Just a bit confused by what cpuz shows. Mainl the core speed? Should this not be 3gig? Just noticed cpuz has my multi as 6, in bios it's 9?

Prime has been stable until now where 1 core gets an error after 15 or so minutes, the others were fine for about the 2 hours it was going. Do i now need to up the vcore slightly?

Finally my ram is set to default in bios so i assume i need to manually set the timings.

What should the following be set too:

Voltage is currently defualt should I change this?
Dram frequency currently 499 should this be 800?
FSB

ram currently 2:3
Cas (CL) currently 5 think this should be 4
Ras to cas delay (trcd) currently 5 think this should be 4
Ras precharge (trp) currrently 5 think this should be 4
Cycle time (tras) currently 18, think this should be 12

Command Rate 2T should be 1T ?

CHeers for any help guys below are screenies of CPUZ, CPU an RAM

you need to switch off the speed stepping C1E etc etc in the bios as this throttle the cpu from a x9 multi to a x6 multi.

I owuld leave most of the ram settings on the default.

Also yes - probably need to up the vcore as that it likely to cause instability

Ive been reading the ram should be 1:1 FSB

RAM

After reading a bit the only thing im confused about is what the DRAM Frequency should be.

Could someone just answer me if dram frequency should be 400 as its x 2, or 800 ?

The rest I have found out myself.

From this link, http://forums.majorgeeks.com/showthread.php?t=124316 :-

1T vs 2T refers to command per clock cycle, IIRC. Obviously, 1T is better, than 2T, if your system can handle it.

I am not sure which settings for the processor you have, but I definitely would switch any Intel dynamic based speed adjustment stuff OFF (I thinkthe setting was Intel Speedstep). Not sure if I switched off C1E. I may have initially then re-enabled it. Not sure, can give you more info if you need it.

Your question about the RAM, and the frequency it runs at. Well, I have an E6600 at 3GHz (so thats 333 with a 9x multi) and I am running the RAM linked and synced (i.e. 1:1) which means my 800 MHz RAM is running at 666MHz. To answer your question, that is 333 MHz for each stick because its DDR2 RAM. So yes, 400 MHz will mean 800 MHz effective.

Hope this helps

Thankyou, that's all i needed to know. I need to turn of c1e an EIST, that's what was making cpuz confuse me.

My ram can go on 1:1 aswell.

Cheers!

No problem.

Since my first post I have sorted everything an got 3.4 stable overclock. One thing I need to ask is where in the Abit IP-35 bios can I set command rate to 1T. It's currently on 2T but I can't find it anywhere.
