G.SKILL PIS F3-17600CL7D-4GBPIS 2200 7-10-10-28 1.65V P55 Series

[zsamz_]

Will these work effectively on an AMD platform?

i was @ 1920mhz 6-9-8-24 1.65v fully stable on rampage extreme so i think they will do even tighter timings on amd since its good for 2300mhz cas8 on p55

[bro20000]

Well Impressed with this memory just trying it on Asus P6X58D Premium here my results up to now!

[hiwa]

nice 2000 6-9-6 what about vdimm?

[bro20000]

1.66Vdimm!

[borec]

nice

[bro20000]

Just cant go any higher now when clocked to 2000Mhz my NB clocks are 4000Mhz thats my limit what ever i do it crashs to go any higher!

[kow_ciller]

These are some pretty nice sticks (vdimm @ 1.72v)
2550mhz @ cas7 sure does look nice

[hiwa]

crazy nice sticks you got there man
2550 Cl7 is awsome, Aircooling?

[nolonger]

How do these compare to the F3-18400CL8D-4GBPIS? I'm buying one of them tomorrow, gotta decide which one.

[Kentaro]

I 'm curious about it as well. Havnet seen any review about it. I was going to order the 2400MHZ CL9 kits, but it is a little bit shortage right now. I 'm also thinking which one I should go, maybe 2300 MHz just can go higher frequency.

they are also PSC but binned ICs

[nolonger]

they are also PSC but binned ICs

So basically they're the same memory, just the 2300MHz will probably run at a higher frequency, but more relaxed timings?

[hiwa]

they based on same IC
2400 are handpicked from Gskill or .... laboratory between a lot of PSC ICs

[Kentaro]

I agree with it. Even they are made of the same IC, but higher spec means special binned IC. I think 2400mhz kits should be really good binned IC. G.Skill and Patriot just released 2500Mhz kits, but haven't seen any review or post about it yet.

i'll post 2500 kit soon

Hey!

I am testing right now these sticks:
http://www.gskill.com/products.php?index=257&c1=1&c2=3
Platvorm is:
AMD X6 1055T
Gigabyte 790FXTA-UD5
2x2GB G.Skill 2300MHz CL8

And these stick dont like CL6 and CL7.
800MHz CL7 is max, even 850MHz CL7 donät boot.
I tried 1.65v- 1.72V and no help.

Then I put in these cruical rams:
http://www.crucial.com/store/partspe...=BL12864TN1608
And 800MHz CL6 no problem.

So these G.skill 2300MHz rams are not elpida?
Max voltage for them?
I hoped that these bad boys can do 900MHz CL6.

Vdimm don't help you
here is a quick test on AMD
http://www.xtremesystems.org/forums/...d.php?t=234689
,2200 don't goes well on AMD platform, you need hyper or Micron or wait for new Flare kit can run 2000 7-9-7

[borec]

mine can´t go higher than 1700 CL797 1,65V on AMD plaform (790X + 965BE). More Vdimm on this sticks don´t help as Hiwa say
D9GTS can go 1800 CL6 on AMD... But 2,3V

try tWL.................................8 and try 1.68 to 1.72 on Vdimm 8GB need higher Vdimm and sometimes need higher VTT dipend on ur CPU

[jojodancer]

Thanks for the fast reply.

Is Vdimm = DRAM voltage

Other Timming settings needed to be adjusted as well?

[hiwa]

yes Vdimm = Dram voltage
no you don't need anyother sub setting, try just +1 on tWL

[jojodancer]

Looks like 2 x 2gb kit are much more easy to tame than 4 x 2gb kit!!!!

I still have trouble to stable this setup at Prime.
