    I found me a nice P4PE mobo, (asus) and i decided to try and play a little with oc. What is the absolute best ddr memory there is when it comes to heavy oc? I know it is mutch luck involved here but i still want to get the best modules available.

    Also i have another ques, the Thermaltake Volcano 7+ is suposed to handle speeds up to 3 ghz, anyone ever used this cooling solution on faster speeds than that? Or is it just not good enough above 3..? Do i have to use water?
    Thx in advance for any help on this..

    I run the volcano 7+ on my p4's, the 2.8 is at 3.49ghz right now with it vcore at 1.8. On the 2.53 it'll be at after this next reboot, 3.21ghz (like she normally is) vcore at 1.675, and both cpu temps are rather low. the 2.8 running at 3.49 is currently at 35 C (full load, seti running) and the 2.53 was at last night when I answered a question similar, inbetween 33 C under 100% load.

    As far as ram goes, the faster the better, right? Not always. As you say, results will vary, but the two 256mb sticks of samsung ctl memory modules ddr333 run 458mhz w/ some tweaking for stability, and 438mhz w/o tweaking memory. (both speeds, stable.) You should have your hand at the corsair xms3500 cas1.5 ram for best oc'ng in my opinion (general). I run two of those sticks in the 2.8, and I've yet to max them out yet (have had to push the ram really yet (actually have yet to break 433mhz heh, highest got to yet is 432mhz)... so you'll be good to go with that ram... but here, at least, that corsair ultra low latency xms memory is 70 bucks more expensive per 512mb stick than what i payed for the samsung ram, and it's turned out to be stable at 183mhz fsb w/ some tweaking.

    Well i found XMS 3500 cas2, but not any cas 1,5 as you mentioned. But one of those modules should be able to get things rolling pretty good don't you think?

    Corsair XMS3500 512Mb DDR PC3500 CAS2 434MHz with Heatsink

    Btw i belive i've read somewhere on the forum that it's better to use one module rather than two when building a comp for oc.
    Do you agree?

    :cheers:

    Absolutely. I've always had better luck oc'ng w/ only 1 stick of ram.

    OK, I do have a dual-channel motherboard. Corsair makes an "optimized" twin-pack of DDR, but it's "only" PC3200. Is it worth any hassle I may have synching the two sticks over just getting a matched set that's a touch slower?

    We can't get those twin packs here yet though I've had no probs with usin' XMS3500 sticks (except the need to jump the memory voltage first with more standard memory). The XMS3200 does work fine in them though you'll have to start cuttin' back on the insane timings at about 210MHz. :devil win

    Woops I forgot but ya did tell me that those insane settin's wern't available on that mobo right? :confused:

    I just read a review of those twin-packs as well as the "Low-Latency" Corsair PC3200, and the reviewer's opinion was that the extra money wasn't worth it for the Low-Latency sticker, as you could get the same timings with the standard Corsair XMS, although not automatically by SPD, by tweaking the BIOS. All I'd really like to know is...what memory can I use that I don't have to swap sticks with? I'll still tweak the BIOS, but it's a pain to have to do it every time I reboot (That's the problem I was having with the OCZ). A hotrod that you have to pushstart ain't no fun....:cheers:

    It doesn't happen to me all the time but basically this is already overclocked memory which is why ya have to sometimes jumpstart it.
