Which parts to choose for a system (multiuser, multitask, with more RAM) ? - Page 3

post #21 of 27
Thread Starter 
I know and have used Memtest86+, MHDD, WD and Seagate diagnostic tools (for HDDs) - all from bootable CDs, and I think I've used Prime95 for Win some time ago (I don't recall the test settings though for Prime95).
Are these good?
What other tests could be done for mobo testing? SSD testing (if it is worth)? Videocard test? Component integration test? Windows 7 hardware compatibility test?

Thanks!

Right after I got the PC I ran a memtest86+ v.4.20. After ~7hours of standard test I had 2 passes and 3rd pass in progress with one error from test #4 (Moving inversions, random pattern) frown.gif



Continuing the test to overnight hadn't revealed any more errors. After 15 hours there were 4 passes completed with only the one error mentioned above.

I then ran only test #4, and after almost 2 hours of test #4 a similar error has shown up:



Some part(s) must be incompatible or defective?.. Does it look like bad RAM or maybe other component(s)? The retailer that assembled and tested the PC says it has successfully passed various tests, and suggests to take the whole PC for testing (or take the RAM modules for testing and give me 2GB RAM for the time of testing so that I had a "working machine").
drool.gif Most importantly I need a reliably working machine, and then I need it ASAP... What can I do? What would be the best option for me now?

Note: the VGA is Gigabyte Radeon HD 7770 (GV-R777OC-1GD).

Oh shoot, I'm really sorry that happened!
That is certainly the RAM then. Simply return the RAM and exchange for a new set. I don't know of any better / more reliable RAM so it sounds like you just got unlucky. I'm glad you ran memtest to find that problem now rather than later on when you are trying to use the computer!

Oh, thanks for your reply, but I've just noticed it..

I was very confused should I leave them RAM only or the whole PC, and I left just the RAM yesterday. Before that I was able to detect that error only on the first day, two times. Second day - I couldn't detect it. This was really confusing. Looked similar to the previous build intermittent errors. I left the RAM for them and asked to test longer. So nervous...

A minute ago (that's about a day after I've left the RAM for them to test) I've got response from the retailer/support that they found problems in that RAM set (wow thumb.gif ), so they have another new set of RAM ready for me. I think it's Corsair the same model again.

The thing is I had bought a Corsair 2x4GB set DDR3 SODIMM for a tablet PC before here two weeks ago, it turned out it was bad, they RMA replaced it, and it again was bad, so I asked to refund, and bought Kingston 2x4GB SODIMM, which looks like is working perfectly (although I'm skeptical lately about things like "working hardware", could be LOL... I was even googling another day about technology and frustration, doh!).

So I'm now doubting about this desktop PC - maybe it would be better to stay away from Corsair? I.e. don't take Corsair set from them, and ask for a Kingston one? On the other hand, if so, I don't see which one would be good for me, and at what speed would it be running:

KHX21C11T3K4/32X - http://www.skytech.lt/khx21c11t3k432x-ddr3-kingston-hyperx-beast-32gb-4x8gb-2133mhz-cl11-165v-p-140981.html
KHX16C9T3K4/32X - http://www.skytech.lt/khx16c9t3k432x-ddr3-kingston-hyperx-beast-32gb-4x8gb-1600mhz-cl9-165v-p-138502.html
Kingston price is higher roughly by 100Lt.
Or maybe even take 2x 2x8GB (Crucial or Kingston, instead of Corsair)
Here is the list I'm looking at.

Which option would you choose (same model 4x8 Corsair 1600 CL9, Kingston 4x8 2133 CL11, Kingston 4x8 1600 CL9, or a pair of those 2x8 sets)? What would be the difference in realiability/compatibility/performance?

Many thanks!..

Sorry for the late reply -
I've never used Kingston RAM before, but I know that it is just as reputable. Since that brand has worked well for you in the past, trading in for Kingston would work smile.gif
Between those two sets, they are pretty similar in performance (the first one has a higher speed but higher latency, it's a pretty even trade off). I will say 1600MHz with CL 9 is more likely to work from the start; higher speeds sometimes require more configuration, and that's not what you want right now!

Thx for the reply, I was waiting for it smile.gif
While you're at this - would Kingston's 1.65V voltage make any problems? Like - would it stress my mobo and/or PSU more than 1.5V RAM sets do? 1.65V is near the maximum voltage limit that can be supplied by this motherboard, am I correct?
I see that my current Corsair memory ("CMZ32GX3M4A1600C9: DDR3 Corsair Vengeance Black 32GB (4x8GB) 1600MHz CL9, XMP1.3") and some Crucial 2x8GB sets (like this one) use 1.5V.

Edit1: I see KHX16C9T3K4/32X says it's actually not 1.65V, but 1.5V on Kingston site, this must be correct voltage?:
Quote:
Standard 1G X 64 Non-ECC 1600MHz 240-pin Unbuffered DIMM (DDR3, 1.5V, CL9, FBGA, Gold)

Edit2: On the other hand, it's weird that a faster module is cheaper (803Lt vs 847Lt). Would it really make any problems running KHX21C11T3K4/32X at the designed 2133MHz clock and/or at 1600MHz (underclocked)?

Yeah, I don't personally like 1.65V RAM because more than that can damage the memory controller in the CPU (doesn't matter for the motherboard though). 1.5V is the official maximum voltage supported for memory when using an Ivy Bridge CPU, but lots of people use 1.65V memory anyway.

I think I would trust the manufactures page; that makes more sense to me (1.65V for 1600MHz seemed odd to me originally, but the 1.65V for 2133MHz is more common). Almost always, 1.65V 2133MHz CL11 RAM will run at 1.5V 1600MHz CL9 (that is, 9-9-9-24 timings) perfectly. But again, you are trying to get a problem free computer here so I don't really recommend it tongue.gif

I personally would try my luck with a new set of Corsair RAM again, and if that fails as well get the Kingston 1600MHz.
