Corsair XMS PC4000 (Hynix D43) - Should this ram work at stock speeds?

Recommended Posts

Hi,

 

has anyone tried if the Corsair XMS Twinx PC4000 (2x 512mb) with Hynix D43 chips would work at 200MHz?

The timings for 250Mhz are 3-4-4-8. Is it possible that they run at 3-3-3-8 if I not overclock them? The memory needs a vdimm of 2,75V.

 

Which bios should I flash, 623-2 or 623-3?

You could get lucky with the right timings but should it be unstable it is the chip.

I am not sure about this particular Corsair module but the cheapo generics with D43 i had did 270 @ 3-4-4-8 and around 230 @ 2.5-3-3-7

 

Hope this helps...

I tried a pair of Hynix D43 sticks in my Ultra D. In my old P4 board they did 2-3-3-6 @ 200MHz dual channel and 3-4-4-8 @ 280MHz. In the Ultra D they did 205 3-3-3-8 dual. Thats the best they could do.

#1 i've never had much luck with Hynix based memory on the DFI NF4

 

#2 ive had even less luck with anything Corsair makes on the DFI NF4 other than my 3-year old real BH-5 (which works like a freakin champ)

 

 

Hynix + P4 = massive overclocks (I have some old OCZ 4400 Hynix that does 291FSB 1:1 on my Lanparty 875B, but wont even do 201FSB on my DFI NF4)

Have had at least 2 friends who clocked Corsair TCCD pretty high on nF4 Ultra-D with Winchester/Venice cpu's, so that's not that bad after all ;)

unfortunately those are just 2 or 3 out of at least 100 that we've had to steer away from Corsair memory since they had nothing but problems with it...once they moved on to another brand of memory, the problems went away (some had psu issues also)

I managed to oc my Kingston Value Ram (Hynix BT D 43 chipset) to 240MHz @ 2.5-3-3-3 @ 2.9vdimm. It was mentest v1.55 and Prime 95 stable but It would crush during gaming. I could not boot up my comp on default timing at DDR200Mhz but cold boot up and load into windows at 240Mhz. The most 'Weird' RAM that I ever used.

There is a list:

I own the Corsair XMS Twinx PC4000 Rev. 1.1.

 

I hope I'll be able to run them at 200MHz with 3-3-3-8. That's my aim.

Maybe I will buy new ram when I want to overclock.

 

Am I right, that there is no need to flash a beta bios if I won't overclock?

 

 

btw: On my old Abit AV8 I reached 225MHz at 3-3-3-8 with these modules and on my current MSI K8N Neo2 Platinum I set the timings to 3-4-4-8. Lower timings let the computer crash (I don't tested different bioses, maybe I new bios will solve this).
