Very bad RAM benchmark performance (DDR3 12800 1600MHz)

post #1 of 14
Thread Starter 
EDIT: Turns out my RAM was performing just fine, the benchmark results I had were misleading, and actually slightly above average for memory like this!

Therefore I have kept the memory and have been happy with their performance. They are still running perfectly a year later.



Hi all, I'm new on this forum but I was hoping you could help me out.

I've recently built a new PC and overclocked it, but my RAM (Avexir Blitz 6GB (3x2GB) DDR3 PC3-12800C8) is performing far below the average. I've ran benchmark tests with PerformanceTest 8 (PassMark).

The test results were all much worse than benchmark results for similar RAM. They were barely better than an old Kingston PC2-6400 memory.

Performance Test 8 Memory Mark
Overall Memory Mark: 1280
Database Operations: 43.8 (thousand per sec)
Read Cached: 15617 MB/s
Read Uncached: 5768 MB/s
Write: 4194 MB/s
Available RAM: 3926MB
Latency: 65.9ns (Most RAM sticks have a latency of 20-35ns)
Threaded: 15106 (The only result that is actually decent)


Is my RAM faulty or just really bad? Or is the benchmark test just wrong/irrelevant?

PC Specs:
Memory: Avexir Blitz 6GB (3x2GB) DDR3 PC3-12800C8
Motherboard: MSI 970A-G46
Processor: AMD FX-6300
GPU: MSI HD 7850 1GB OC
HDD: Seagate ST 500GB 5900RPM (a very bad hard drive)
Operating System: Windows 7 Home Premium 64bit

Further notes: I've tested the RAM with various bios settings: stock (default) (3.5GHz CPU), and with custom overclocked settings (4.2GHz CPU) as well as with the OC Genie II auto-overclock. RAM performance is improved with overclocking, but only by a hundred or so points. Ram voltage is on 1.652V (closest I can get to 1.65V, the manufacturer spec)

I've also tested ram with various settings: 1333MHz, 1500MHz and 1600MHz, and with different timings (8-9-8-24, 9-9-9-24, 8-8-8-24). Doesn't make much difference.

My 3 memory sticks are in slots 2, 3 and 4 of the motherboard because my CPU heatsink blocks the first ram slot on my motherboard.

My Hard drive is also terrible - well, it's an old 5900rpm seagate which needs replacing when I can afford to, I dunno if that would affect memory results?

Thanks for any help.

Welcome to OCN smile.gif

With the above setup (slots 2,3 & 4), you're in single-channel mode. Try just 2 sticks.

Here's how to put your rig in your sig:

Ah, well I was afraid of that. I'll try it out! (In slots 2 and 4)

Thanks for the the link as well smile.gif

Just tried it out with 2 sticks, the performance is slightly better but still poor.

Changes
Latency down to 59ns from 65.
Write speed up to 5248 from 4194 MB/s
Read cached up to 15847 (from 15617) MB/s
Read uncached up to 6995 (from 5768) MB/s

I suppose this would provide better slightly gaming performance than with 3 sticks (since games tend not to use too much memory) , but the results are still rather low.

Yesterday my PC started freezing up after a few hours of gaming, it got gradually worse until it was almost unplayable.

Today I reset the BIOS back to default, and everything seems to be working fine again. I have gone back to my overclock settings and it's working fine.

Would the freezing up be caused by the memory, or an unstable overclock?

Did a memtest today, passed with no errors. Would it be safe to assume the RAM is working correctly but is just low quality? It was cheap after all.
Would getting a better brand of memory give any noticeable performance gains? I would go for dual channel instead of tri-channel if I did change.

How long did you run the memtest?.

Not too long, just 41 minutes. It was just the first test.

Running just one pass is not enough. But if you're not getting any Bsod's, I think you're ram is okey thumb.gif
Could you try and overclock the NB, to see if it helps.
