** Help needed ** CellShock DDR

[PWee]

Did post this else where on XS but was the wrong place i think.

I have recently bought some Cellshock pc4000 ram to go with my opty144 i have @ 290x9 (2.6ghz)

I bought this cell shock because i was looking at the DDR2 cellshock reviews and results and they were amazing!! so i bough me some of there DDR for my system.

Basically im stuck on overclocking them. Stock they are 500mhz @ 2.5v 3,4,4,8. Im stuck at 260mhz max! thats only 10mhz more tha stock. Any help?

As posted on Overclock.co.uk -

Help!!!! :cry:

At the moment i have only been able to acheive a 10mhz overclock! :?

Very confused as i think this ram is e tbh. Though i must be doing something wrong, i just must be!

260 @ 3,4,4,8 1T stock volts
It can boot into windows @ 270 with 3,5,5,9 2T @ 2.8v even i must be a tard


Settings at 260mhz ram

+20mhz without tuning timings, all automatic in bios except std timings 3/4/4/7.
In BIOS : ram @ 2,5v and cpu @ vAuto

Hmmm, that SPD is similar to the G.Skill HZ DDR sticks, which were TCCD I think. The trick with them is less vdimm. I run mine 270 MHz 3-4-4-8 2.6v (rated 2.8v) with my x2 4600; give it a try.

My bad, the HZ is Samsung UCCC too. Good sticks tho, still use them. Yeah, looked familiar.
