New gaming PC, memory errors and won't preform to factory specifications

[allanon1965]

if its PC3200, he shouldnt have to lower it to PC2700 for it to be stable, if it has too, its defective....period, however I would try running it at 2T versus 1T the performance is negligible, and I have tested this theory out on my own machine....does OCZ guarrantee 1T in the specs? if not what do they claim it does? Run it at that and then see what it does...

you said: So I had to override the settings and change it to what it is suppose to be. (2-3-2-5-1T)
the specs says 2T so try it at 2-3-2-5 2T and see what it does...

Well. On their website it doesnt say either way if it can run in 1T or 2T. I just assumed that it can run in 1T being that even cheap value ram can run with a command rate of 1T.

Right now I am loosing up the timings. Its at 2-3-3-7 right now and its testings while Im at school. 2-3-2-6 failed, so did 2-3-3-6. So now im trying 2-3-3-7.

Does anyone know what the settings I am suppose to set the ram to other than the 2-3-2-5 1T? There are like a dozen other tweakable settings in my bios. I am starting to think some of thouse settings have auto'ed wrong and thats what is messing it up.


Thanks.

Make sure your motherboard isn't doing a mild overclock by default. Mine does, and I had to turn that crap off.

I have the same memory by the way and it is running at 2-3-2-5 at 2.5v on my mobo.

If you have to significantly jack the voltage to make the rated timings, I'd RMA it.

Oh, fyi, the ram is 2T, not 1T and says so right on the newegg site. Just use the link you posted, click on detailed spec, and then note the CAS latency.

I see no where on newegg or their site where it says the Command rate.

OCZ site says...

2-3-2-5
(CAS-TRCD-TRP-TRAS)

Newegg says:

Timing 2-3-2-5

if it doesn't work right RMA it.

Im trying to figure out if its my mobo, my settings or my RAM.

Okay, so you keep posting about RAM timings. Time to cowboy up and take control of your troubleshooting process. You should have already contacted OCZ or visited their support forum. I did a search using (what I presume is) the model number for your RAM. Took me 5 seconds to find this: Recommended settings for 2GB OCZ 2-3-2-5 DDR. Note that they are using a DFI board. Do your own search and see if other Epox users have posted their settings, as your board may not have all the available settings that the DFI does.

You'll clearly see that the RAM is able to run 1T timings. Now, if the memory fails Memtest86(+) at the recommended timings, then clearly you have an issue with the memory or the motherboard. Send the RAM back to OCZ and let them determine if the RAM is faulty. If the RAM checks out okay, then perhaps your Epox does not want to run 1T (for whatever reason.)

Don't waste time trying to find settings that will work because the bottom line is that if the RAM won't run the advertised timings there is a hardware problem somewhere.

:thumbsup:

Yeah. I contacted OCZ and visted their forum to post a message. I put the RAM in my dads PC and he is getting the same errors (command rate of 1T or 2T.)

Ive now ruled out that my mobo isnt the problem. I will be returning the RAM.

Do you think I should RMA it back to newegg or send it into OCZ?

 

[TriggerHappy101]

Well I used that link you gave me and I had to change all of the RAM timings in the bios. I set them all to what they said in that thread and now windows won't boot. Just hangs once I press "Start windows normally" and even when I try booting in safemode.

I however do not have some timings that were in the thread like "Dram drive strength, Dram data drive strength, and dram response time.

And for the "refresh period (Tref)" the thread has 3120 for the setting, my selections are like 7.8us and 14.2us or 4.6us (i forget the exact number.)

Im pretty sure my RAM is shot now.

The other guy on OCZ forum gave me some new timings. Gonna try thouse out.

 

[ElFenix]

something i noticed with corsair is that their ram is rated faster on pentium 4 systems than athlon systems. i wonder if the same could be happening for OCZ?

 

[TriggerHappy101]

The guy on OCZ forum gave me these settings, and they work! I ran Memtest 86 for like 14 hours with 19 passes. No errors!

1T/2T Memory timing = 1T
CAS # latency (TCL) = 2
RAS# to CAS# delay (TRCD) = 3
Min RAS# active time (TRAS) = 5 (although I recommend 7 or 8)
Row precharge time (TRP) = 2
Row to row delay (TRRD) = 3 or 2
Write recovery time (twr) = 2 or 3
Write to read delay (Twtr) = 2 or 1
Row cycle time (trc) = 11
Read to write time (trwt) = 4 or 3
Refresh rate (tref) = Auto
Read preamble value = Auto
Async latncey value = Auto
Idle cycle limit = 32 or 64
Dynamic idle cycle counter = disabled
R/W queue bypasscount = 16x
Bypass max = 4x
Dram bank interleaving = enabled
DQS skew value = auto or the default value
Burst Length = disabled (4 bursts)
S/W memory hole remapping = disabled
H/W memory hole remapping = disabled

Correction:

Seems like my mobo is defective. Wont run prime95 for more than a minute and my games bomb out on me 30 seconds of getting into it.

It is a problem with running in dual channel.
