OC Report: Geil Ultra DDR2 PC2 6400 CL4 2x1GB

[Xtreme Addict]

Hi everyone today I would like to introduce very popular model of ram memory in Poland. Relatively high clockers with medium price

Some photos:







Now lets start this play

Test configuration



all A/C

Setting alpha latency...

Horrible job

I found out that this combination is most stable in all cases
(in P5B Deluxe bios)
3/4/5
3/4/5
3/4/5
13
3
6
13
13
10

First try -> 2,2v (2,25v in bios) 3-3-3-13

Max stable for 24/7



Losing timings to "4-4-4-13"



And last lap... 5-5-5-13

And here I was quite disappointed, losing timings didn't gave any mayor boost in MHz. I was forced to raise vdimm to 2,3v real (2,35v in bios). And it bore this score...



Raising vdimm with 4-4-4-13/3-3-3-13 didn't cause any extra MHz, but only stability issue

This 3 scores are entirely stable for 24/7

In addition these sticks don't boot at 2,4v real (2,45v in bios). And on 2,35v (2,4v in bios) they occur errors in Stress Prime 2004 ram test.

Summing up

This memory is based on Elpida chips.
