I can't tell if my memory is bad.

[Nimblor]

I bought 4gb of DDR400 (kingston hyperx KHX3200k2/26 4x1gb) sticks, slapped them in my sig rig and booted up. Trememdous improvement in speed and smoothness especially with chrome. Naturally I wanted to re-oc my machine and got it up to 2.7mhz no problem, Prime95 stable for about 20 minutes, until I got bored. YAY! Except my HTT was at 900mhz which was weird and I did not remember how to fix that. To get the 2.7 mhz I had to run a 3/4 memory divider which was ok. I pushed for MOAR!! but i ran into problems.

THEN I decided to memtest86+ my sticks which is easy because v1.65 is in my bios.. got an error in test #3. Ok I figured I better run stock settings on the memory so I set everything to auto in the bios and ran it again. Then my cmos battery died, luckily it is the same battery as in my garage door opener; my wife will be mad on Monday but hey... prioriteeeez!! Reset bios, reboot, set to auto, run memtest86+ over night. Red screen in the morning. What the fork! bunch of errors found.

Now I tried to take out all the sticks except 1, reboot gives me 3 lights and slowly repeating long beep of doom. Same with 2 and 3 sticks too and the 1 stick moved to slot 2. So I am ready to kill something right about now.

I want to use this rig with WHS but I am not sure about the memory. I have no problems in windows prime95 is chugging away. Do I really need to be worried about memtest throwing errors? What is the worst that could happen?

AUTO wont mean that your timing are set OK in the bios.

Manual your memory speed/timing/volts to your ram rated spec. Then memtest again

I might need some help with that part.. how do I make my bios



look like http://www.valueram.com/datasheets/KHX3200K2_2G.pdf???

It has been a while since I have been messing with this stuff.

Thanks!!!

 

[Mr.Scott]

Set those sub timings back to auto first. Those timings are even tight for BH-5.

 

[Nimblor]

That was an earlier mem test when I was monkeying around with some settings I found on the internet. Here is what the memtest looks like with everything at auto. Note the speed is off...???

[redduc900]

Is the DRAM voltage set to 2.6V w/ the DRAM frequency at DDR-400?

 

[Nimblor]

I think I have the voltage set correctly. See below. I am not sure about locking the speed...

 

[Mr.Scott]

You have to enter 'DRAM Configuration' to remove the divider you're on. Also set the timings manually to 3-3-3-8. Probably won't matter anyway. The speed and timings you're running are the #2 JEDEC spec. You have one or more bad sticks. Test them one at a time.

 

[Nimblor]

Mr. Scott! I did a lot of reading and found that the kingston hyperx and dfi sli-dr expert have a reputation for disagreement. I saw Tech Tweaker's thread here http://www.overclockers.com/forums/showthread.php?t=714435

Lots of references out there to DFI street which is now gone I was about to give up much like you did in "Into the Darkness" but just before I gave up the ship I found this genie bios info about hyperx sticks

http://forums.overclockersclub.com/index.php?showtopic=138112&page=2

With those settings I was able to get memtest to show the ram at ddr400 and it got past test 3... but not test 5 : . I added some voltage which reduced the test 5 errors but at 2.81v I stopped because there were still to many and my memory was getting warm.

I decided to let DFI take the wheel and set the timing to auto... 2.71v... it worked!! my victory is in pictures below. CPUZ says I am running at 2.5-3-3-7-2T which will do. No errors in memtest and booting windows like my strong pimp hand tells it how to boot!

2.71v is not bad right? Memory seems cool.

Thanks for your help good people! My rig is going to make a swell server.

The highlight reel-
Memtest passed at ddr401 ... say what!!!

Bios settings-
Hopefully these are helpful to someone!

 

[Mr.Scott]

I was a DFI Street member.

The Kingston DFI inconsistencies depended on what IC's were on the sticks. I have HyperX BH-5 sticks that work just fine on all of my DFI boards.
Glad you found a way to get it going.
You can go to 2.85v on those sticks if you have to.
