8rda6+ pro nforce2 RAID--I HATE IT- 3 problems!

[warrenwrench]

I did check the SPD on the GSkill I RMA'd before I sent it back. It was the PC4400LE and the SPD was 3-4-4-8. It was supposed to be 2.5-3-3-7. I asked the GSkill rep about it and he said you have to set it manually. If I'm not mistaken, The SPD should be what it is rated at. Yes there is RAM that will run at better timings then it was rated at(that is part of overclocking) but the SPD should be what it is rated at. The GSill rep also said that the PC4400LE will not run at 2-2-2-5 at anything above 200fsb.

That stuff is delicious. I might be willing to trade the memory in my sig for a regular supply of sausage for the next year! lol!

Exactly, this is the city in the south of Poland, where Krakowska Sucha (direct translation "dry" ) sausage is made. Hmmmm, I must think about your proposal really seriously.

cheers


As to G.Skill's by SPD timings : LE sticks are theoretically rated 2-2-2-5 at FSB200 and 2.5-3-3-7 at FSB275, but as far as I can recall the readings in Everest it wasn't the case.

I think my SPD timings were similar to those of yours. I'm almost 100% sure, that Everest showed 3-6-6-X at FSB275 (or 277, as in your case). This is something really peculiar, since you have LC memory sticks and my SPD timings should be similar to those of warrenwrench. Of course, this doesn't change the fact, that these SPD values aren't correct.

A few facts : some friends of mine have exactly the same memory sticks and they use them in their nForce3 and nFroce4 systems - these sticks are capable of doing FSB(or HTT) 300MHz at 2.5-3-3-7 and all of my friends are honestly very pleased with them. I'm gonna ask them for the SPD readings, since I've always had some strange SPD problems with Epox motherboards, which I didn't use to have with Abit.

On the other hand, my mobo properly read my Twinmos memory sticks SPD timings : 2.5-4-4-10 at FSB250 (the only stored value).

The G.Skill rep seems to give very strange answers : although I have serious problems at FSB220 and higher, my system is rock stable at FSB210 with 2-2-2-11 timings and 2.77v Vdimm (at FSB200 2.65v is enough to operate stably).

When it comes to tight timings, most manufacturers don't set the SPD to those tight timings. I suspect it's because there are boards out there that can't manage the tight timings when set via SPD. Hence the manufacturers set timings that will work, rather than deal with large numbers of returns because a motherboard gets things wrong.

[jnansley]

Oh yes. It would be very silly for manufacturers to set their SPD to values that some motherboards cannot boot. I can definitely agree that manufacturers would NOT want to set the SPD as low as possible.

I think the very first Corsair LL sticks started this problem in the industry - obviously there is no way to change the tmings in the BIOS if they won't even boot as default.

And if I'm not mistaken, one of the 8RDA+ BIOS updates was supposed to correct that problem by ignoring 2-2-2 SPD's.

I do know that a lot of my motherboards default to an "Auto" setting which is a conservative value that is NOT the "SPD" setting.

I don't recall my EPoX SPD settings with the Mushkin memory, but my ABIT with the Corsair PC3200XL set by SPD 2-2-2-5.

The SPD is from the memory not the mainboard.

The SPD gives a timing default for a given clock frequency, but does not always have to be set at the full capability of the memory. This is useful where a memory controller isn't capable of the full capability of the memory - it gives a stable base to work from.

I think you all guys are right, but on the other hand 2.5-4-4-8 at FSB200 and 3-6-6-12 at FSB275 are the most conservative by SPD timings I have ever seen. They more look like DDR2 timings, not DDR1.

Look, the company guarantees 2-2-2-5 at FSB200 and 2.5-3-3-7 at FSB275 for all newer Intel and AMD64 systems. Btw. have a look at the recommended motherboards.
I personally think the difference between the guaranteed timings and those by SPD is simply at least strange.
