What is the best RAM for 231 MHz FSB (DDR 462) with as low latencies as possible?

[Cold Generation]

I read the test of Mushkin PC3500 Level II RAM over
at Anandtech, and they managed 2-2-2-6 at DDR 400.

This is not yet possible at DDR 462, right?

If I want to run one of the "Game" options in my
IC7 BIOS, can I use for example OCZ PC3700 Gold sticks?

Like the "Streetracer" option which sets the latencies to 2-3-2-5?

The thing is, I have a 2.6C which I want to run
at 3.0 at 1:1 settings, this means 231 MHz FSB.

So can the OCZ PC3700 Gold do Streetracer at DDR462? Not likely, huh?

The IC7 BIOS can provide VRAM up to 2.8V.

Thanks for any suggestions!

IIRC-
OCZ can't run any form of Game acc.
Corsair can run up to turbo.
most rams can't run Street Racer.
there's probably like, only 2-3 ram types in the world that can run F1

XMS3500 (mine anyway) will do it up to DDR500, 2-2-2-5 but it depends on the motherboard and you need voltage (see my outdated sig). On Epox boards such as the 4PEA+ and 4PCA3+ they will do it, but for some reason, it's actually easier on the dual channel 4PCA3+ (will do it with less voltage).

On your IC7 at 2.8 volts at best you will be able to do DDR440 at 2-2-2-5, if the board likes Corsair (which I hear it does). That's what I've done on a P4C800-E and 4PCA3+.

I will be testing an IC7-MaxIII pretty soon and I'm anxious to see how well my XMS3500 will fare on it.

RolandC,

My ocz gold pc3700 2x256 can run F1 at 240FSB/1:1/2.85v at 2,3,3,6 on my IC7-G with my 3.0c. Actually, both of my sets of 2x256 pc3700 gold can do F1 upto 240FSB.

I recommend the ocz gold pc3700 2x256 or the mushkin level II pc3500 for the best possible timings at that speed.

hmm,
i remember reading somewhere that corsair's PC3700 edged out OCZ's 3700 gold because to corsair could do turbo and the OCZ couldn't....
perhapes BT can jump in here and clear things up

Wow, that`s nice!

But 2.85V on an IC7-G? How is that possible?
Isn`t that board limited to 2.8V as the IC-7 is?

[Dr.2K]

RolandC,

Well i am sure you are aware that not all sticks are created eual but from my experience with corsair, geil, kingston and some of the cheap stuff, ocz has always been at the top more often then not. For these 865PE and 875 intel chipsets, ocz has the top memory at this time from my experience and not to mention top notch customer support.

Cold Generation,

My IC7-G overvolts the vdimm 2.8v to 2.85 and so does my gigabyte KNXP 2.8v to 2.9v

[RolandC]

well, i'm not going to haggle with you because i can't find the review atm
if i stumble accross it i'll give you guys the link.

With my 3.0c and Mushkin 2 X 512 Performance Level II Black----I got a Stable 231 FSB timings 2.5,7,3,3 GAT at Turbo, Enhanced, 5, Disabled, Disabled.

I have a volt modded IC7 and was feeding the RAM 2.95 VDIMM

Lowest timings I could get

Am going to try the OCZ PC3700 Gold----but it only comes in 256 sticks

The best 512 sticks I know of are the Mushkin

I really want 1 meg of RAM and I hear that the IC7 has problems with all 4 Dimm slots occupied.

[Dr.2K]

I was thinking about getting some of those mushkin LII pc3200 or the LII pc3500 after reading the review by prometheus, but still debating wether it would give me better timings then my quad matched set of ocz gold pc3700. On my Abit IC7-G (bios 1.5)with 4 dimm slots and 1 gig of ocz gold pc3700 the best overclock and stability I was able to get was 230FSB/1:1/2,3,3,7/Turbo. But on my gigabyte KNXP I am able to get 235FSB/1:1/2,3,3,6. And 240FSB is my limit with my 3.0c with 2x256Mb ocz gold pc3700 on either board, but on the Abit with 2x256 ocz gold pc3700 I am able to reach 240FSB/1:1/2,3,3,6/F1.





I am wondering if the mushkins will give me better timings of 2,2,2,5/6 at these speeds.

[johnrr6]

I couldnt get a 1:1 with the 3500 Muskin higher than 234-----and it really wasn't stable till I backed it down to 231.

Best timings I could get was 2.5,7,3,3

Best GAT was Turbo, Enhanced, 5, Disabled, Disabled

This was with a volt modded IC7 which gives me a nice VDIMM of 2.95

So----in answer to your question----don't think the Mushkin will give you what you want-----it didn't for me.

I see you ran 4 x 256 OCZ PC3700 Gold-----and PAT was still enabled! But it also looks like your overclock suffered until you went 2 X 256-----then.......

WOW! 240 FSB @ 1:1 on a 3.0c with GAT at F1!!!!!

That's OVER a 3.6 overclock with the best settings GAT can give!! EXACTLY what I am looking to achieve on my 3.0c

What was your VDIMM, Vcore, and what were your exact GAT settings??

If only they made that PC3700 in 512 sticks!! PERFECT for a 3.0c

I'm going to try a dual pack-----but I really want 1 meg of RAM----guess I'll have to compromise.

Finally----did you use two dual packs of the 3700 gold----or did you find a quad pack-------or just individual modules???

Thanks for any help-----do you mind if I PM you??

John

[Dr.2K]

Not at all johnrr6, pm me anytime. All vdimm on the ic7-g were at 2.85v(slight overvolt; 2.9v on knxp)and vcore (1.6v both boards). "PAT" is enabled with 4x256 (Turbo only with 4 slots) on the IC7-G no matter what since GAT is enabled, but on the knxp in order to keep PAT enabled you have to overclock with setfsb or clockgenerator thru windows and leave clock settings in the bios to under 210FSB. And yes, your overall top overclock will suffer if you use 4 sticks instead of 2 (harder to synchronize 4 sticks then 2), so for pure benching i use only 2 sticks and for gaming will use 4. Exact GAT settings were:

F1
Auto
Auto
Disabled
Disabled

OCZ cant make a 512Mb on the pc3700 gold because they are already double sided on the 256 so it would be very difficult if not impossible to to fit the large samsung chips on the board to make a 512 module.

But I have to inform you that getting here was not easy and was a very long searching and waiting process (2-3 months). I have to tell you that i first had ocz gold in a dual set retail and then bought another dual set retail also. But when i used both sets together in 4 dimm slots on either the ic7-g or the knxp, i was only able to get 2.5,3,3,7 timings. But both sets worked flawlessly individually(2x256) at 2,3,3,6 upto 240FSB/1:1/F1 on the IC7-G. So I gave ocz a call and asked them if i could have them replace my 4 sticks with a matched quad set that will do Cas2,3,3,7 upto 240-250FSB 1:1. And what do you know they came up with a quad set for me that was pretested together that will run upto 240FSB at Cas2 1:1.

IMO, I feel with 2x256MB the computer is more.....shall i say quicker and feels more responsive then with 4 sticks. Also, remember i am on water cooling and not air.

Also, thanks for the info on the mushkins johnrr6, now that puts me more at ease of, should I? or shouldnt I? LOL.

[eva2000]

Dr.2k but if i recall isn't you IC7-G vdimm modded to support higher vdimm options as well ?

[Dr.2K]

Hi eva, no i think you have mixed up with someone else . For myself, i didnt want to take the whole dam water cooling setup out and do the delicate mod. Plus I aint that great at soldering, . And when my top left northbridge mounting clip popped off i just super glued it back on, hehe. Works great actually and been holding fast for last month or two. But, if i ever decide to get me a 2.4c then I will seriously have to look into doing the volt mod and/or get the IC7 Max3. But with prescott on the way, I doubt that I will go that route. Waiting for the 3.6 prescott.

hmm must be someone else with IC7-G hehe
