CellShock PC2-6400 (DDR2-800) 2GB Kit

Test Setup & Settings

Test Setup

Processor: Intel Core2Duo E6700 "Conroe"
Motherboard: Asus Commando P965 (unmodded)
Graphics Card: BFG 8800GTS Overclocked (550mhz / 1600mhz)
Hard Disks: 2x Hitachi Deskstar 80gb SATA-II 8mb Cache (RAID0)
Power Supply: Enermax Infiniti 720w
Operating System: Windows XP x64


As with all DDR2 reviews on Overclock3D the CellShock modules were subjected to a series of benchmark tests under several different configurations. The configurations used tested the memory's ability to run at high frequencies, tight timings and also ensured that that it could run with 100% stability at stock settings.

Stock - DDR2-800 (400mhz) / 2.1v / 4-4-4-12


With a stock voltage of 2.1v and latencies at 4-4-4-12 the CellShock modules actually have the tightest stock latencies of any kit we've tested here at OC3D so far. For this reason I was slightly worried that I might run into stability issues. However, I'm pleased to say that the modules were 100% stable at this setting, passing a 32m SuperPI run and several hours of ORTHOS stress testing. With this in mind, I set out to find how much further the latencies could be tightened....

Low Latency - DDR2-800 (400mhz) / 2.2v / 3-3-4-10


By increasing the voltage to the maximum warranted 2.2v I was able to lower the CellShock modules down to a hugely impressive 3-3-4-10 latency setting. Going lower than this did still allow me to boot into Windows, but failed half way through a SuperPI run. I'm pretty sure that increasing the voltage a notch or two would have seen even better results.

High Frequency - DDR2-1192 (596mhz) / 2.2v / 5-5-5-15


With the memory still set to 2.2v I loosened the timings to 5-5-5-15 and set about trying to find the maximum frequency that the CellShock DDR2-800 kit was capable of. After a little tweaking and several stability tests, the modules fell only a few MHZ of DDR2-1200 - A 50% overclock!! Simply amazing for a kit rated at DDR2-800. Yet again, I'm sure that with a little extra voltage (2.3-2.35v) these modules would have been capable of much more.

i wasnt expecting such a drastic overclock

....i think the likes of OCZ, corsair etc have some challange on there hands now Quote

Very very well written review, Nice read!

And does that look like good ram or what? Quote

Mr. Smith
My dominators are dead so i need some interim ram, I found these for £100 so sounds like i'll order!

Nice reviewQuote

Its even cheaper if you go here:

Overclockers.co.uk - 88 quid

Bargainous i say!

Saying that, i've just snaffled some of the 4-4-4-12 PC8000 Cellshock sticks off ebay for 87 quid, so the bargains are out there if you shop around

The PC8000's have micron D9GKX chips, which are apparently better than those on the 6400's, so should overclock even harder so i'm told Quote

Ye but if you buy from Overclockers then you get the worst service in the uk...do you want that?

I know I don't....Quote

heh probably better service than i'll get by buying off ebay - well... maybe...Quote
