So not to confuse ... these are a dfferent set of the same 2gigHZ's ... and I'm very happy, my other sticks (swapped with a friend who didn't care) were good but with pop's help I like these better ... guess you could say he tried to explain all this to me already!

sent out the first set of this ram to newegg today on a RMA, no way to pass memtest and no way where they stable at ddr500 or even 400 for that matter.

If this next set is bad im going to OCZ 2gb pc4000 kits.

I'm running my HZ's at just 255 mhz. What would be the tightest timings i could try for these? Maybe 3-4-3-6 or 3-3-3-7? Do I have to modify other bios settings if I aim for tighter timings instead of high clock speeds?

yeah it is me!

i will come here more :)

 

do i need to have sig too???

 

I had a technician tell me that these sticks are capable of doing between 180-280MHz average. There is one out of a thousand that can do 300MHz. Plus i've seen G.SKILL owners here haven't alot more settings modified than what G.SKILL technician has confirmed? Also these sticks are a pain to use on dividers. If i have my sticks stable @264MHz 1:1 and try to push the CPU up and leave the MEM at 264MHz with a divider it won't work with those timings. I really hope these sticks like the Opty's, cause 165 is on it's way this week. Wish me luck!

This might be a simple question but I'm curious.

 

 

There is a setting called Refresh Period (Tref) and it has settings listed as 200 1.95 or 100 1.95. I have an expert board and can't seem to find these specific settings listed.

 

 

I have the G.Skill PC4000 HZ ram and so far I got it up to 284 before BSODing using "Thunda's" settings. except with 3684 for that setting.

Those settings are different in A64Tweaker or any software you use to define it. If you go into the Bios, it would be 3120, so on and so on...so don't look for those goofy numbers. Does that help? Now if you're trying to find out the actual number, now that's going to be some hard work, unless there is an easier way to do it, anyone?

3-4-3-6 is the best I can do at my speed here and at 1T, but I don't have a great set of sticks. As soon as I try 3-3-3-6 or 3-4-3-5 they crap out.

Burky,

I think someone got these sticks @ 2.5-3-3-6 or something like that, isn't that crazy or what?

That is crazy. Like I say, I got a bad set; they won't even do 255mhz at 1T.

I've tried dropping all the timings down one in my sig (seperately) but it's no go.

 

What speed did they get such timings like that for?

Oh that's funny. It's silly to have those as stable settings when the exact bios number setting isn't known.

I'm not sure, but i got mine @264MHz so far, Booooooooooooooooooooo! I hope this kit plays nice when my Opteron 165 arrives this Friday. :)
