I know that some people have had good experiences with Patriot XBLK ddr600 memory, but I have had nothing but problems with this memory since I first got my first gig (512 x 2). First of all, I can't get my comp stable wit 300mhz fsb even with the multi down to like 8. Furthermore, when sporting like 2 gigs (512 x 4), I can barely get my comp stable above 250 and at times 240. This is trash for memory which is like $200 a gig and should be providing be with a ridiculous amount of overhead. Anyway, I'm thinking about junking this memory and by "junking", I mean selling the <expletives> on ebay for whatever I can get. The question I pose to you all then is: What is the best memory out there for reaching like 300 fsb or what memory do you guys recommend for this? The mem doesn't have to be ddr600 but the higher ddr, the more overhead, OBVIOUSLY!!
( I probably should have left that part out so as to not offend anyone). I really want 2 gigs because quantity provides better performance in games and such. However, my budget is kind of tight these days, so the cheaper the better. Anyway, thanks in advance guys.

G skill as for the 4 sticks that is alot of load on the mem controller.

Do you have an LDT voltage on the board? If so, crank that up a bit as that's for the IMC, so might help. Also, have you gone in and tweaked all the smaller timings in the bios for the memory? Some of these can have a real impact on stability. If you haven't, I'd recommend doing this first.

Are you using the recommended timings for ddr600?

Ok, I really don't consider myself a noob as far as overclocking is concerned but I am certainly not an expert so I have to admit I'm not sure what you mean by the LDT voltage and IMC. I've tweaked everything from the timings, to v-dimm, etc, and I still can't get my system stable. I've run memtest a million times, testing each new setting. Can you please clearify what you mean? Thanks man.

The IMC is the Integrated Memory Controller on A64s. The LDT voltage is for the IMC and is normally set at 1.2v. Not sure if it's present on the Asus boards, but I would have thought so. Try raising to 1.3 or 1.4v. This is normally near the chipset voltage in the bios.

Have you tweaked all the timings other than the main 4 ones as well? These quite often are overlooked, but essential to gaining high overclocks.

LDT is a voltage option in dfi bios.

LDT normal voltage is 1.2 so look in bios for something like that.
Try raising to 1.3 or 1.4 volts.
You will also have to raise the chipset voltage from 1.5 to 1.6 or 1.7 volts.

I don't think the Asus board has those settings for Chipset, and IMC voltage control. At least my A8N-SLI Deluxe doesn't. I imagine the premium doesn't as well, same bios and all. This board just doesn't overclock well above 240. I can't get it stable above 240 either.
Whats your CPU voltage at though?

Dont spread lies.
My board clocks up to 340mhz.
So you are doing something WRONG.
There is the option for LDT and IMC voltage but its named differnetly.
HTT voltage (chipset) tho it only goes to 1.65 i think and another one i forget the name and too lazy to get into the bios but its right beside it.

Must be with the premium then. My deluxe only has voltage adjustments for DDR and CPU. Thats its! There is no HTT voltage. My CPU voltage is only adjustable to 1.55 max. So it won't go above 240. So, no lies, just calling it the way I see it. Or, maybe....maybe!! Oh, maybe you could tell me what I'm doing wrong!!

Yeah, I'm with mastacator. I have the HTT voltage up to the max and CPU voltage maxed out as well at 1.55 (sucks, huh!). Anyway, I haven't really played with the other mem timings besides the main four so I'll give that a shot, although I have no idea how those really affect things. Anymore recommendations for some highly oc'able memory guys? Thanks for all the input also.

Your motherboard will have a really hard time running 300 mhz. I've seen at least 2 reviews and several members struggle to get anything over 250 mhz on a 1:1 ratio.

You wouldn't want to do it on a daily basis...but try using one stick of memory. That seems to be what I see most often. The more sticks plugged in...the lower the max HTT/FSB.
which kind of makes sense as there are more "stops" for the "bus" to make

As for DDR 600 memory...I have only had experience with G-Skill as well and that system worked up to 280ish HTT.
