HELP :: New G.Skill Zx Ram problem!

harris1986 · 4 Jun 2006 at 23:11

Ok guys just received my G.skill 2*1gb pc3200 zx kit and popped them in my system and for some reason they won't run on a divider above 140 but will run stock timings. I have tried on a 166 divider with slacker timings and upping volts to 2.9v and still no joy (doesn't even get to windows loading screen). I put my 2*512mb pc3200 ocz gold's in and i can run 180 dividers lol with the same cpu clock (260mhz*10).

Anyone have any ideas? or is it rma time for the ram?

Try dropping the voltage to 2.6/2.7. These sticks dont like a lot of volts.

k i'l give it a go when i get home from work this afternoon and let you know how it goes! just find it strange that it will run the timings just doesn't like the 166/180 dividers but with cpu running at stock (200*10) it will run on a 200 divider

I can only run the 133 & 166 dividers. Whether thats down the the mem, the mobo/bios or the optys mem controller i dont know but fortunately 133/166 is all i need so i've not investigated further. As trojan says tho i'd certainly try lower volts, the best results i've had have been at 2.6/2.7v (currently 208mhz 2 3 2 5 2.6v 166 divider, orange slots, 623 bios)

kk noted, i just thought at the time it was lack of volts not allowing me to get into windows, i'l check my bios revision too!

I found my set of OCZ 3200 Plat and G.Skill ZX kits liked different dividers. Again, not sure if this is memory or on-die memory controller.

I stuck with the G.Skill in the end as it worked on a convenient divider (see sig).

I also had some weirdness whereby I couldn't use a divider when the memory was set to 2-3-2 timings, even when it was ~ 200 Mhz. Again, see sig for the timings I used in the end. I'm convinced this is all due to the on-die memory controller when overclocking hard.

I agree with other people - they don't like high volts. 2.7 was sweet spot for me. 2.8 and higher just errored.

rite-o i think my g.skill is nackered! i just reset cmos and tried putting the ram on a divider of 200 with stock timings (2-3-2-5) and the cpu at it's stock 200*10 setting, every time i would get to windows loading screen and just before it's about to come to desktop it reboots! i then popped my OCZ back in and it boots up fine. Anyone else think this is RMA time?

Doesn't sound good. Leave everything at stock and run memtest for a few hours.

Yup.

Interesting....

Will have to try my ZX at lower volts. Still got it set at 2.8v from when My OCZ was in there.

ok guys update for you here! i re-flashed my bios (to the latest) and now ram is working on a 166 and 180 divider. However boot times are getting a tad silly, i currently have my ram running on the 166 divider and 2.5-3-3-8 and 216mhz now my comp gets to my windows sign on screen quickly but after i enter my password it takes ages to get to desktop (First my background appears, then eventually my desktop appears).
