Do I have yanked-over memory?

[iwantanewcomputer]

I can OC the FSB from 200 to 240 stable with memclock setting at 5:3 (so 240*5/3 = 400MHz DDR) with everything else stock settings, then i think the proc gives out. when I try with 1:1 the highest my FSB will go is 210 and then not even stable playing games. Same results with the mem voltage on 2.8 instead of 2.6

am I right in thinking it's the memory's fault, even though it's supposed to be 466MHz?Also should I try playing with the timings-listed at 3-4-4-8

Yeah, sounds like memory. Set ur divider to I:I and increaase FSB, then, after saving changes in BIOS, boot immediately into memtest to check ur ram. Maybe it isn't running/performing up to spec's.

what kind of memory is it? if you are unsure of what you bought, use CPU-Z to find out what chips your really running and let us know.

is the sytem in question in your sig? are you sure its not the cpu holding you back? lower the multiplier really low so your only testing the ram.

thanks for the advice but,

i'm not sure how to boot into memtest

it'snot the cpu holding me back...setting it to 1/2 the multiplier it won't boot windows at any higher fsb than 215, not entirely stable there, so mem at <430 is my max for DDR 466

this is the mem

also can i rule out any probs with chipset or something cause i can get a decent oc with 5:3 mem ratio but almost nothing with 2:1

 

[AWhackWhiteBoy]

what timings are you tring to run,thats most likely your problem.

 

[iwantanewcomputer]

it's set to auto so i think its 3-4-4-8

IIRC, you d/l the proggie to ur HD, insert floppy disk, then click on it and it will create a bootable floppy.

I just can't remember if it will d/l directley to a floppy, but I think so. You'll know when you hit d/l.

Leave the floppy in (make sure floppy is first bootable device in BIOS, if not make the change when you are in there adjusting/increasing the FSB). When you save and exit BIOS after increasing the FSB, you will automatically boot directly into memtest86.

It's a very handy proggie for OCer's. Otherwise you don't what is at fault and end up increasing voltage willy-nilly to ram, cpu or chipset.

If your ram passes memtest, which I don't think it will. Increase vdimm by small increaments until it does. Or rma it, telling them it failed memtest.

Can do...i wouldn't want to go willy nilly on the voltages.
thanks, but i want you to know that now i have to pull a floppy drive out of a 9 year old dell p133 and hook it up

LOL, That's why we keep those 9 yr old pc's around. They eventually become good for something

 

[iwantanewcomputer]

yeah, dell's aren't much good for anything else, the bios won't even let you overclock the FSB, what fun are they without OC'ing?

anywho, i ran memtest 86 overnight and it just had a column of 1000's down the page. I tried hitting escape and the other commands they had there and nothing happened so i think it crashed. Don't know if it is cause of disk failure corrupt program or what but i will try again

 

[iwantanewcomputer]

it passed memtest 86 3 times, but just won't work with decent timings, i'll increase them some more and see what i can do

 

[Fern]

Can you up the vdimm? Might help you stable with better timings.

 

[iwantanewcomputer]

it was at max, 2.8
I got it to boot windows with fsb 220, memory 2:1 when i set the timings to 3-6-6-8

also, i noticed the heat spreaders were very hot while under loadat default voltage. i held 2 case temp sensors against it for a while and it read 45 C. i think these are pretty accurate too cause the spreader was too hot to hold on to long. i find this troubling cause my proccesor is ususally under 45 while under load with stock hs. mobo temp is like 30. i will try memtest with higher speeds and the high latency settings.

in the meantime...wtf?

 

[iwantanewcomputer]

memtest 86 shows one fine, one has errors out the wazoo for a fsb of 205 and higher with stock timings and latencies. that explains it, time to rma.

thanks 4 help guys

why exactly would you set the divider to 1:1?

I am running a really similar system to this guy and having similar problems. Asus A8V Delux, OCZ PC3700 EB memory. I can't seem to take my FSB up at all past 200 without instability. I've been using a 2:1 multiplier, but I am still not sure how the multiplier works as I have heard very conflicting answers from people.

Somebody told me to try an FSB of 233mhz with a ratio of 1:1 to get a 466mhz DDR clock. I tried it, it booted up (my wifi card didn't work) but CPU-Z reported a memory speed of 116.5mhz. Why would a divider of 1:1 make my memory run at HALF the speed of the FSB????

 

[iwantanewcomputer]

i think he meant use a 2:1 ratio. on my board at least 2:1 means the memory speed is twice the fsb... 200 fsb => ddr400 233fsb=>ddr466 i think other brand boards use 1:1 to mean 200fsb=>ddr400. as for the half speed i'm lost. tried it on mine and at a fsb=233 and 1:1 i got 233 try using a different prog like motherboard monitor to see if that was just cpuz

good luck, i'm going to send my kingston mem back now that my psu just died
