problems with new gskill ram

[phrowzen]

welp.. ddr520 @ 2.7V 2.5-4-4-10 gets over 200 errors in about 9 minutes running constant test #5 in memtest86. I will soon test each stick invidividually, to see if both can actually DO DDR550...

If I can conclude that 1 stick will not do DDR550, does that mean that I can rule out power supply as a bottleneck?

 

[phrowzen]

Wow.

I've got quite the conclusion. After swapping the dimm slots to find no luck, I then went and flashed 1.41 beta bios. I proceeded to test the usual DDR550 2.5-4-4-10 @ 2.6-2.85V, with as usual no success. As I was about to enter 2.85V, I wondered if the new BIOS unlocked any other vdimm options. Not remembering seeing 2.50V or 2.55V on my previous BIOS, i selected 2.50V. Needless to say, its been memtesting test5 for over 20 minutes now @ DDR550 2.5-4-4-10 without error.

I know TCCD doesnt like high voltages, but, im running it lower than spec! Anyways, I'll take what I can get, if this is successful ill try 2.5-3-3-7. I'm just scared to walk upstairs and check to see if it has failed

 

[phrowzen]

Well,

I had reason to be scared. Failed after about 22 mins, 25 passes

Trying 2.55V, doubtful itll work.

try each stick individually at totally stock speeds. if one fails but the other passes, you might just have a bad stick. then try the working one to see if it runs at its rated speeds and timings, 2.85v.
if they both fail at stock, it could be your PSU. dont even bother with lower voltages until you find out if you just have a bad stick.

Anyway did you try upping the ram voltage? I know 6mhz doesn't seem like a big OC but anything up to 2.85v is perfectly safe for any ram. And don't be afraid to up the timings, A64 performance doesn't really rely on ram timings at all.

yeah it does, talk to zebo or run superpi.
i agree with the 2.85v part though, unless u are using some crappy value ram. when u are trying to find your rams max oc use 2.85, then when u get it running at the speed you want it, lower the volts and run memtest; see if it passes. if it does, repeat until you are running at the lowest voltages posible stabily.
EDIT: Also, don't_use half multis for the HTT or the CPU. my MSI won't even post when the LDT is at 2.5x and even if yours does it probably wont be stable.

 

[phrowzen]

Well,

I just finished testing both modules individually at DDR550 2.5-3-3-7 1T (275HTT*9CPU mult) My cpu is capable of doing this as I have prime 95'ed on small fft at 11x240 for over 31 hours.

I tested the ram at the above speeds at a combination of voltages between 2.60V and 2.85V as they are rated.

I do not know anyone with a performance power supply around, I like to think mine is pretty good, an enermax 435W.

In my machine I have:

Enermax 435W
A64 3500+ s939 90nm
MSI K8N Neo2 Platinum
BFG Geforce 6800GT OC @ 400/1100
2x36.0GB WD 10,000RPM S-ATA Raptors RAID 0
Audigy 2
Nexus-S Satellite Tuner
1x80GB IDE IBM HDD
1x30GB IDE Maxtor HDD
1xLG 48x cd burner
1xPioneer DVR-108 dvd burner

I do not believe this is too overpowering for an enermax 435W, I suppose I could unplug everything and try again, but doesnt all the devices I have listed above run on the 12V rail?

Thoughts appreciated. My supplier has already allowed for the return of the modules, but if it turns out they are not defective I am responsible for return shipping as well as 20% "b.s." fee.

Vid card and cpu are the 2 big power drawers on the +12v....fans draw off them and drive motors do....so unless harddrives are other drives are spinning up I think you are fine...

Have you tried a touch more vcore??? I notice that what is table at same speed but say a 133divider versus a 200divider took another notch of vcore to get stable.... I bet you already tried this...

I say if you cannot get even on eof the sticks to run at rated speed just send them back and get something else....probably not gskill...

I cant get those arseholes to email me back....I am told to rma them but they wont give me a number and I want that before I send 280 dollars through the mail. I have contacted NA rep and now the main website...1-1/2 weeks of no answers not even a form email....Now I am fing pissed...I will now officially RMA every stick that does not running advertised speed...

 

[phrowzen]

Hey,

I did try an overvid of 3.3%, but that did not work. I suppose I could try higher. As well, I should be able to RMA via the eBay store that I purchased them from, so hopefully I won't have nearly as much hassle, although I feel very bad for you in your case.

On the side, I live in a relatively small town, and even all the computer stores in the city next to me have no sufficient system capable of testing these modules before I send them back. Mainly all I want to utilize is their power supply, as I am charged a 20% restocking fee for returning it. Likewise as you said I suppose I can try some more vcore, but just to note as I said earlier, there didnt appear to be any problems running 2x512 DDR510 2.5-4-4-10. However, as soon as i lept to DDR520, thats when some errors began to show earlier on. (For all I know, DDR510 may have failed if I let it run longer than the 20 minutes I let it.)

I got ahold of them buy calling the reps cell phone number in one of the emails...sending them out today for a monday delivery...

Like I said these things are rated for a prescott system from my findings...I seriously doubt unless we get some excellent sticks we may not be able to get 2 sticks to run cas 2.5,3,3,7 on A64 machines..I will find out with another 2 sticks....

 

[phrowzen]

Hey,

Well I'm glad you finally got your RMA . Good luck with the return and the new modules.

I just finished testing DDR550 2x512MB 2.75V (if i recall) and 3-4-4-10, again, a fail.

If possible would you also provide me with the cell phone number in private message, should things with my supplier go wrong?

Thanks,
phrowzen

hmm...tested out my G.Skill 1GBLE earlier today, and got similar results. It would get errors in Memtest no matter what the setting was at 277mhz (Rated PC4400 speeds). I will run at 255 at 2.5-3-3-7 with no problems though. I wonder if I should RMA too?!? Newegg doesn't seem to have any more LE's in stock at the moment.

That's not entirely true. I'm not sure about which batch you got from, but all of OCZ's TCCDs from the last few months have all worked well with 2.75-2.85v. In fact, with the MSI K8N Neo2 flashed to the latest BIOS, I have gotten 285HTT consistently at 3x LDT and 2.5-3-3-10 1T timings. Try testing one stick at a time. Maybe one of your sticks might be holding you back.

 

[phrowzen]

John, yes the modules were already tested individually. I could not get either stick to run DDR550 2.5-3-3-7 without failing. This is anywhere between 2.60V and 2.85V. I should hopefully have these modules sent back out by monday. I'm just rather dissapointed as I would have expected these modules be tested at this speeds before being sent out from the manufacturing plant. As far as I know I have nearly an identical testbed as what they use.

[JohnAn2112]

Then that would definatley warrant an RMA in my book. I hope GSkill is willing to help you out with that.

 

[phrowzen]

I posted on their forum, and they seem to be willing to exchange. But, I am trying first to just exchange with the company in which I purchased from, it may be a bit faster process. I am still hoping it is not my power supply that could cause such a problem, as a few people in this thread have suggested it to be a possibility. Again, I have an enermax 435w, which from what i know it is the 3.3V rail that supplies voltage to the ram. This rail usually operates around 3.18-3.23V.
