Bad memory or bad board? Need opinions

Re: Bad memory or bad board? Need opinions

Well, the board did not like 5-5-5-15 with a +.10 OverVoltage. It went into an endless reboot cycle that I couldn't break out of... had to clear the CMOS again to get it to boot up.

But it ran all night in MemTest at 5-7-7-21, so I guess that's what I'm staying with!

Not sure why I can't get the advertised speeds, but so long as I'm not crashing I'll live.

Thanks again!

Oh well, though maybe you could squeez some more ?00MB/s with lower latency, not bad at all as it is.

Re: Bad memory or bad board? Need opinions

Yeah, maybe I will play with it some more when I have another computer and can afford downtime : ) Thanks again for all the help!

Re: Bad memory or bad board? Need opinions

If set to auto x48 sets looser than epp ram timings too.

Generally recommended to set pci Express at 100, but that might be for overclocking, so pci doesn't change.

In ram memset image tRD ("Performance level") is shown as 6, but ram u r using shows 7? tRD ("Performance level")has a major influence on mem speed/latency, followed by primary timings and tRFC, therefore the other ram may well be faster. U may want to try maxxmem comparison?

Fast Graphics Booster did not affect any benchmark scores for my overclocked rig, but may do something for others???

Must be a Gigabyte thing, then. Doesn't run at the tighter timings, that's for sure!!!

Where are you seeing tRD/Performance Level is 7 for the RAM? I'm looking in the MemSet pics, but I don't see a 7 anywhere...

Re: Bad memory or bad board? Need opinions

In MemSet it's 6, I think he means the tRD 7 in your sig.

Re: Bad memory or bad board? Need opinions

Ah! That must be from before I cleared and reset everything

Re: Bad memory or bad board? Need opinions

You got it Chike, one thing saying tRD7 and another 6, thought sngbrdb had two different spec sets of ram.

You mentioned trying ram volts at +.1 which is 1.9v. Wondering if you tried adding more, up to the rated maximum? 2.3v would be +.5, and I should caution that anything over 2.1 probably needs ram fans. Possibly raising that voltage might allow 5-5-5-15.

You probably have tried it, but just checking.

Re: Bad memory or bad board? Need opinions

Hmm, the default setting is 'Normal', which gives me a voltage of 2.256... assumed that +.1 would give me 2.356, are you saying that's wrong? Would certainly explain why I couldn't boot, but why would the base voltage be 1.8v?

I actually do have a RAM fan, works pretty well, need it, too, since these guys cook at 2.256

Re: Bad memory or bad board? Need opinions

The up to +0.1 I suggested in post #12 was for MCH OverVoltage not DDR2 OverVoltage.

[sngbrdb]

Re: Bad memory or bad board? Need opinions

Ah! I will try that tonight. Though I'm still confused on the DDR2 OverVoltage, was bumping it to +0.1 really setting it to 1.9v? Cause that would sure be a problem, would explain why it wouldn't even boot, 5-5-5-15 @ 1.9v. Confused about why it's based off of 1.8v and not the 2.256v it picks on normal.

Re: Bad memory or bad board? Need opinions

Yes I believe so, but you can try with 2.4 memory multiplier for DDR-800 which might boot with 1.9v and check PC Health.

Re: Bad memory or bad board? Need opinions

Chike is right saying it should not need much extra mch for 2 x 1GB ram.

Hope you've got some airflow around the ram for over 2.1v 'cause that can heat it up. +.3 is 2.1v

Did it pick those volts at 1066? At 800 it would probably say 1.8. In memset/spd, note the voltages at bottom used for different speeds.

Have i got this right? You have two sets of Patriot ram. One set is rated at 2.1v, 5-5-5-9 and the other is 2.3v, 5-5-5-15?

That would be because the ic's used in the first set were not available when the second set were made, and different ones are used in the newer ones. The 2.1v, 5-5-5-9 would appear faster for less voltage and thus probably has better quality ic's.

Sensors often report lower voltages than set in bios, and different programs reading them can vary too. Slight variations are not usually any cause for concern.
