OC Report: G.skill F2-8000CL5D-4GBPI

[Xtreme Addict]

Hi folks This day is something special - quite fresh new G.skill model of memory. It belongs to new line with extremely efficient heatsinks. It not use any heatpipes, any other technologies like liquid metal or something like that. It's pure custom design of aluminium (not materials almost as aluminiun ). They are quite wide with some wild roller-coasters which cross themselves This memory is really cold! So this new design surely isn't only marketing attack

Pictures and naked photos





















From my experience (but there is no rule actually, please study results of Mushkin ), (and please, trust me, I had lots of memory in my hands ), ICs starting from "x" are the best. They prefer lower vdimm and clocks very high. Next are "r", which are in the middle of this branch. They like high voltages (up to 2.35v, they even boot on 2.4v, when "x" or "t" series stop booting at all). And the last one which I possessed ever (mind 2x2 GB sets) where "t" and they clocked acceptably and prefer low vdimm (about 2.15v).


Testing Configuration

E8200 Q808A314
Asus Blitz Formula (latest beta BIOS)
GeCube HD2900XT
Maxtor 80GB SATA
Pentagram 1050W ES
Windows XP (My Hitachi HDD is dead and with it also Vista )

Tests with CAS3 I skipped as minding 2x2 GB sets it is utter nonsense. CAS4 is much more common, but Powerchip 2x2 GB don't like CAS4 so +/- 815 is max.

It's retail set.

But CAS5 is something much different



Barrier 1066 MHz DDR passed 2.25v from bios.

Sum up,

Unfortunately with new design abilities of overclocking didn't raise but still G.skill is keeping up with the others (1080 MHz DDR is very good result!). New heatspreads are very efficient, good looking and without any problems we can mount four sticks in motherboard. Very nice move G.skill

(Personally now I simply must test some Mushkin with eVCI Cooling, the battle begins )

Nice 4GiB-Kit
Why they can't present a "true" Pi-kit, like 600 Mhz 4-4-4 out of the box for Super Pi? That would be cool!

[Xtreme Addict]

with 2x2 it is impossible

[Hyperhorn]

Yes I know, but they should present a 2GiB-Kit Pi-Edition.
But those DDR2-1000 2*2GiB-kits are very nice for daily use and normal OCing for gamers.

From the results it seems this series is the same as the original PC2 8000 with different heat spreaders

Agreed, i figured such when i first saw these appear.

Thanx for the great review again Miravo...you're a fantastic source of info on 2x2 GB kits & ICs

Thank you,

Soon MOORE to come

Is this the same RAM as mentioned above by -N7- with different heat spreaders?

Yes.
It may not be an identical IC, but it's Powerchips, also starts with an "X", & overclocks are basically the same ballpark.

[Sparx]

Ok
thanks

Trusting Gskill, this is not true.

The Gskill page says that the new series have a new 8layer pcb.

But when its get to maximum clock they are nearly the same. I could reech similar results with PQ, as with PI.

Hey i just got a kit of F2-8000CL5D-4GBPI.

Problem is they wont even run at rated speeds of 1000Mhz at 5-5-5-15

I tried raising the voltage to 2.26, when theyre also rated at 2.0-2.1.

I got a p5e-deluxe with bios 0205.

Anyone got some sort of input here? Did i just get unlucky?

tRFC needs be loose.
Try 55+ initially; tighten later.

hmm i picked up a set of F2-8800CL5D-4GBPI and they arent too bad at all in terms of clocking. 1.86v to run 1139MHz 5-5-5-15-65. I tried to get 1200 to pass memtest but the most i could skew out of test #5 was down to 450 errors. Seems there isn't any more adjustment at that point. Ill try 1180 during the week, my board doesnt like 266mhz strap dividers.
