Poor lighting forced me to use flash on my camera

From irev210's review photo here it seems to be non-Micron based ICs.

Some quick tests of Prime95 v25.4 and a barrage of Everest, Sandra 2008 XII and Super Pi benchmarks all done at 2.1v vdimm.

System

• Intel Core 2 Duo E6850 ES - L723A347 G0
• Scythe Infinity with modded mount + 120x25mm Spire 96cfm fan
• Transpiper heatsink NOT installed
• DFI LP UT P35-T2R 9/13 bios
• 128MB Gainward FX5200 PCI
• 2x2GB G.Skill F2-8000CL5D 4GBPQ 5-5-5-15 2.0-2.1v rated DDR2 kit
• 80GB Hitachi 7K80 SATA

• 700W OCZ GameXStream
• WinXP Pro SP2

CAS5 - Prime95 v25.4
All subtimings on AUTO except tRFC which needed loosening to 48

@stock 500Mhz 5-5-5-15 at 2.10v

@520Mhz 5-5-515 at 2.10v

Seems to be close to max at 2.10v memory voltage so far with AUTO set subtimings and manually set tRFC 48 value.

It's Powerchip.

Everybody seems to be getting similar results. With that consistency the kit indeed is great value for money.

As always, great review George! :toast:

i was tempted to sell my 4x1gb of d9gmh to get these, but 520 just isnt good enough............will keep my d9's

Are you interested in buying??

:up:

Nice testing eva2000! It seems the average 4GBPQ is good for a 10~20MHz OC @CL5. It suprises me that this memory runs better at Trfc=48 on the P35. Denny also tested his memory on a DFI P35.

I could'nt get my system boot with tRFC=48 at 520MHz 5-5-5-15. On my P5B Deluxe 965 I need at least tRFC=50.

I can't wait to see your CL4 tests.

Nice review Eva. :up:

I have my kit now, been doing testing on it since Thursday night. I've actually had better luck on the overclocking side of things than most others have. I'll be posting my review within the next few days.

sweet, look forward to seeing the results.


I am re-testing on gigabyte x38 today :)

irev, how are the results with the x38???

i just ordered this kit, will be here hopefully tuesday.....i will do some tests with the x38

I want to buy these, but I can't find a shop in the Netherlands that provide these kits.
In Germany I can't find a shop which has these kits on stock.
Also not on stock in the shops I searched in the UK (also in UK veery expensive).

Newegg has these on stock and very nice price, but doesn't ship international :(

Anybody any suggestions for a shop that has these kits on stock and can ship it to the Netherlands?

Thnx in advance!

I've been able to hit 900@ 5-4-3-12@2.2v stably with command rate at 1t.:eek:

Gonna see if I can push it further.:) Will post ss later.:)

Oh menn... I really want these modules :D

Somebody please help me find a shop who has these on stock and can ship to the Netherlands, so I can have it asap ;)

www.memoryc.com

They ship anywhere in Europe...if you do order, might i ask you tell them i sent you over to the website.

:-)

yes thnx. I've already contacted them before, but they didn't had in on stock.
But now they do :)

It's a bummer that the currency for Euro - UK Pounds is not good for me :(

Any CL4 results yet?

been too busy.. lots of toys to play with .. will get back to them when i have some more time :)

CL4 gives me bluescreens :(
(@ 850Mhz and 2.1V)

Try 2.2v. Although don't expect to get much higher then that at CL4.

Sorry to bring this thread back from it's slumber

but I'm having issues with this memory and my Abit IP35pro

timings where set 5 5 5 15 in bios with 2.1V-2.2v under vista x64 it seen fine no blue screen but under winXP x64 i keep getting Disk.sys stop: 0X00000050 after bit of research it's now doing little better with 5 5 5 15 TRFC 45 but yesterday i got my first blue screen again after 1 whole day of been blue screen.

my question is if i wanted to run @ DDR 1000 speeds what are the best stable timings should i use for stable system.


got to give to MS looks like vista handles error better then XP.
(i do notice my system bit feels slower then my X2-4400+ running vista 32bit my guess the memory is affecting it cause there both have the same tweaks and system with more Ram should be smooth not to mention 4 cores)


my specs are

Q6600
abit IP35 pro bios 16 B4
8GB of Gskill F2-8000CL5D-4GBPQ
7300le "for now"
Audigy 2 ZS
Dual Antec true 550

i do see timings posted on the first few post but guessing those are set for best performance squeezing out the last MB is there any timings for stability.


thx

PS here a thread i started on abit forums http://forum.uabit.com/showthread.php?t=133965
i blame the board but looks like it's the memory who is to blame

TRFC at 48 or higher. :up:

And in the future, to avoid those problems, always use memtest.

yup, this ram likes higher tRFC values
