Mem Test

[piotrgurin]

I'm doing memtest on G.skill 2x1gig 2325 RAM and ULTRA-D.

 

I'm not too familar with memtest and was wondering, if i get errors does that mean the RAM is defective or that I might have to change something in BIOS?

 

Thanks,

From experience it can mean either, usually though I've just had to take down the FSB, increase the RAM Voltage or loosen the timings.

Gotcha,

 

I'm doing stock speed 200, and auto timings of 2325, I upped the RAM Voltage to 2.7.

 

I've got 8 of these 1x2gig sticks that I bought from Newegg for $185 for my business.

 

The first set I tried game me about 4 errors in 10 mins.

 

The 2nd set I just swapped in seems to be going strong so far.

Try looking at this guide for Memtest. It starts in about the middle of Post 1 over at i4memory.com by EVA2000.

 

The section starts out, so you can find it a little easier.

 

General

 

memtest ain't 100% but you can use memtest to guage the max possible FSB/MEM which is the top limit of what you can expect... since i don't think i've ever experienced windows 100% stability and error free at a speed higher than the highest memtest passable speed

 

therefore

 

max FSB/MEM speed (100% windows error free/stability) <= max FSB/MEM speed (memtest error free)

 

 

My experiences and testing methods

But like stated before your error could be both bad memory or need to change timings, voltage etc...

Also take a look at the overclocking guide and memory guide by ThunDA et.al.

If you are talking about GSKill 2GBZX I have had two sets of these also. For stock (DDR200) try these setting with 2.7-2.8 VDIMM

Row Precharge Time Trp 2

Row Cycle Time Trc 7

Row Refresh Cyc Time Trfc 13

Row to Row Delay Trrd 2

Write Recovery Time Twr 2

Write to Read Delay Twtr 1

Read to Write Delay Trwt 3

Refresh Period Tref 3684

DRAM Bank Interleave E

DQS Skew Control A

DQS Skew Value 0

DRAM Drive Strength 7 (8)

DRAM Data Drive Strength 3 (3)

Max Async Latency 7 (8)

Yep i was, thanks!

 

I''ll try these soon.

Just an FYI if you are running 704-2bta be aware that

 

DRAM DRIVE Strength is lableled a little differently so

 

7 = Weak4

8= Normal4

 

I got some of the above timing info from this thread over at XS here on those sticks of mem.

 

Hope it helps
