Favorite Memory Overclock DDR and DDR-2

I wanted to start another DDR POLL but thought I'd make this simple. With so many brands to choose from, and the introduction of DDR-2, I believe we should share those experiences as well. Hey don't be afraid to admit your a RDRAM lover. Feel free to include any pertinent info such as price, place of purchase Rev.# etc.



Please List the following:
1. Memory brand/model. DDR and/or DDR-2
2. Cas latencies @ best overclock / best overclock
3. Voltage (any Vmods)
4. Motherboard (chipset, BIOS settings/version).


My current favorites are:
Corsair Twin-X1024MB 3200XLPRO
2-2-2-5 @ 200MHz (DDR400) 2-4-4-8 @ 250MHz (DDR500)
2.75V @ 2.85V
Asus P4c800Edlx 875-chipset, SPD, BIOS ver.1017, Chaintech ZNF3-250 SPD DDR Strength-2, SPD, BIOS ver. 0714

Kingston Hyper-X3200 2048MB KHX3200K2/2G
2.5-3-3-6 @ 200MHz (DDR400) 3-4-4-8 @ 250MHz (DDR500)
2.65V @ 2.85V
Asus P4C800Edlx 875, SPD, ver. 1017

OCZ Technology Premiere 4200
2-3-3-6 @ > 230MHz (DDR460) 2.5-4-4-8 @ 285MHz (DDR570)
2.65V @ 2.85V
Abit IC7, Abit IS7, Abit AI7, Asus P4C800Edlx, Epox 4PCA3+ (3.23VDIMM but CPU was a 3.0 at time and board fried after lapping NB)

hi mate
im on GeIL Golden Dragon PC3200 400MHz Dual Channel DDR CAS 2 6-3-3 1T.
currently at 2.5,4,4,8 loose timings as im still raising my fsb on my 2.4c, will start lowering the latencies when i hit a stable oc level hopefully 3.3ghz.

i guess geil isnt the best ram out there, ill post back when i really push the ram to its limits.
lz.

Mushkin good for OC?

Hi,not sure if this is the right thread for this btu I'm new to forums and you guys rule!! I have Mushkin enhanced pc3200 Blue line memory and would like to know if this is good for oc'ing. My sig has my specs. Im new to oc'ing but know a little. What should I change the ratio too? I cant seem to get over 3.1 but have only changed FSB so far. I feel I should be able to go higher as my cpu temps stay pretty low. Around 39 idle 47 load. Any advice? You guys rule!!

It's been a while since I've had my Abit IC7 but here goes. If your running at 3100MHz then your running at 258FSB @ 1:1 ratio (NB/Boot Strap = PSB800). This is excellent for the memory you have, as your running PC3200/DDR400 at PC4000/DDR500 speeds. If you haven't touched anything except the FSB, then your attaining PC4000 speeds at 2.55VDIMM? If so I'm RUNNING (not walking) to get some of that Blue Plate Special Muskin you have.

Download/Save CPUZ and once you open this program click on the Memory tab. This will give you the memory timmings at any (current) speed. At 258FSB I'd bet your running 2-4-4-8. The Samsung IC's used in most Low Latency memory recently are able to run at 2-2-2-5 @ 200FSB and at 2-4-4-8 @ 250FSB. This probably includes your memory, Corsair Twin-X 3200XLPRO, OCZ Platinum 3200, etc.

To test your memory thoroughly I'd get into the BIOS and do several things. First, change the timmings from SPD to Manual 2-2-2-5 (remember 5 = tRAS always the highest number Row Active Time or RAS Pulse Width. Basically the amount of time the Row is open to Data Transfer). Make sure the PCI/AGP is at 33/66 respectively. I downloaded the Manual for the IC7 MAX3 and for some reason it says you have GAT (I thought GAT was only on 865 boards like the IS7)? If you do have GAT leave the GAT settings in AUTO for now and you may have to Disable CPC (Command Per Clock). If you don't have GAT (which I beleive you don't it's just the old IC7 MAX3 manual or a misprint) After you set your BIOS ensuring NB/Boot Strap = 800, and Memory is manually set to 2-2-2-5 riase then FSB. At 2.85VDIMM I'd say those IC's will only hold to 220FSB. That way you'll know how high you can hold the tight timmings.

IF your looking for pure CPU clock speed, then change the memory to SPD, leave GAT on AUTO excet CPC which you Disable and raise the Vcore to 1.575V, and VDIMM to the boards MAX which I beleive is 2.85V. Watch your CPUI temp, it's getting up there. I'd also remove the side panel from the case, I'd bet you a 10C overall drop in system temps.

mushkin pc3500 black level 2. BH-5
Abit NFT-S, 223 FSB (mobo holding me way back)
2.9V, 2-2-2-2.5
Probly the only thing that hasnt dissapointed me in some way yet....
Oh wait, my cpu is still respected too.

PQI PC3200 2-2-2-5
Abit NF7 v2 238MHz Dual Mode
2.6v 2.5-3-3-11

this ram is simply awesome

Kingston Value RAM PC3200 Dual-Channel Pack 2x256
3-4-4-11 @ 261.7MHz (DDR522)
2.85v
Abit NF7-S 2.0, BIOS D25 by -=Merlin=- CPC On

Kingston Value RAM PC3200 Dual-Channel Pack 2x256
3-2-2-11 @ 237.0MHz (DDR474)
2.95v
Abit NF7-S 2.0, BIOS D10 4x4 Turbo by Tictac

Dam that Kingston Valueram may have some hidden tricks under it's sleeve.

I'm testing some OCZ Platinum Ed PC3200 Rev.2 now that does 2-2-2-5 @ DDR400 and 2-3-3-6 @ DDR540 and at just 2.85V yikes! Just when I'd thought I'd tested some of the fastest DDR out there, OCZ comes along, and performs more PCB engineering magic. Look like hiring Dr. Michael Schutte (Lost Circuits) has really paid off. I'll keep you posted on this one.

If you want, I can turn this into a poll, and close the old one here.

Best ram for A64's would be OCZ 3500\3700 EB if you buy now? (buy now for bh-5)
