much useful stuff here, i am looking to upgrade my ram as have vista 64 and asus P5B deluxe.

I currently have 2 gig of generic ddr2 800.

What is the max ddr2 800 I could have (I know the board allows 8 gig but I am thinking that is the slower memory and not 800 spd?)

And does anyone know what the max 1066 speed ram I could have is, I would really want 4 gig of PC8000 DDR2.

I have not been able to find much at Asus, the QVL for memory seems really out of date.

many thanks newbie on board.

Sorry to dig up such an old thread, but I was hoping somebody here could help with a question I have similar to the poster I quoted.

Short Story: Does anybody know of RAM that I could use that will work over 800Mhz (I'd LOVE ~1066Mhz) when using 8GB of RAM on this motherboard?

Long story: I've currently got a Q6600 overclocked in this machine to 3.2Ghz (FSB 358Mhz) running with 8GB of G.Skill RAM (F2-6400CL5D-4GBPQ). When I originally overclocked this machine I kept the ratio 1:1 until I found a nice stable OC. When I tried to push the RAM up past 800Mhz I couldn't get it to work. I put it aside and said "I'll deal with it when I have time" figuring it was a voltage, or timing issue and just required a bit of trial & error.

Well, a year later I finally get around to it and after much headache I found out that most 2GB sticks require a tRFC of 54+. The P5B only allows you to manually set a max value of 42, which is too low. So the only way to use 2GB sticks over 800Mhz is with ones that have the tRFC set to 54 or higher in SPD.

I've heard of the SPD tool that lets you adjust the SPD, but I'm not sure I want to try that (although I may have to) since it could potentially brick the RAM and I can always use it in another computer or sell it. So I'm left with buying new RAM, but I don't know which ones to get. I'm hoping to be able to push near 1066 territory, but thats probably a bit greedy and I'd settle for over 800mhz.

In case it helps, I've been eye-balling the following 2x2GB PC2-8500 (1066Mhz) kits:
G.Skill F2-8500CL5D-4GBPI
Mushkin 996599
Corsair TWIN2X4096-8500C5D
OCZ OCZ2RPR10664GK

Right now I'm leaning towards the OCZ since I saw in their forums that they set all 2GB sticks with a higher tRFC in SPD. I'm in the process of writing to tech support for all of the brands and see if they can tell whether or not it will work on this motherboard, but I'd really like any personal experience you guys may have.

Hi elconejito,

First of all welcome to AT!

I do not run all that much amount of RAM, right now I am running 4 Gb in my system, 4 x 1 Gb Crucial 800 Mhz 1:1.
But since you want to OC, and probably is willing to spend money on memory, just be warned that the chipset 965P will NOT take much advantage from higher clocks, the best shot you could give is running mem assynch (4/5), set FSB @ 400 Mhz and memory running @ 1000 Mhz.
And the quad I had did not go very far, I could achieve 425 Mhz, And it ran very hot, vcore was set beyond the limit I think it is safe. So I gave up of quad Q6600, running back my E6400 @ 3200 Mhz and vcore 1.275.
And as far as I have been reading it is not that easy to run 8 Gb of ram on any system when overclocking, for sure you wont be able to use tight timings, specially in 1066 Mhz. Also the 965P chipset will not give you all the performance you are expecting and speding the money for.
So I think you consider changing the motherboard might give you better results than buying new memory. Just a heads up!
About memory you might look into overclocking section here and other forums also, like XS forums. You might find a lot of info about memories, and results of the overclocking.

Good luck!

G.Skill isn't too bright when it comes to setting SPD it seems, as you've discovered.

I have the same kit as you do in my P5B-D, & yup, same low tRFC = no decent OCing.

All Mushkin has tRFC @ 52 in SPD as far as i know; Greg on the Mushkin forums can confirm that.

Honestly though, getting 8 GB DDR2-1000+ stable on the P5B-D is not going to be an easy situation, if possible at all.

I've tried...it's really not the best board for high clocked 8 GB.

I found that the only ratio that was decently stable over DDR2-1000 w/ 8 GB was 2:3.
4:5 was not for me at all.

If you are @ 358 2:3, that's DDR2-1074...

With some luck, that might work.

I don't recommend bothering though really.

Enjoy your G.Skill 8 GB 1:1, & save the pennies for a 6 or 12 GB DDR3 i7 system

 

[elconejito]

Thanks for the replies folks. That's about what I figured, although i was hoping wasn't the case For what it's worth, I did end up trying the SPDTool and it didn't make one bit of difference. Per some of the forums around (don't recall which I've been on so many can't keep them all straight) I tried upping voltage on northbridge and FSB termination (still don't know what that does) and no luck at all. I tried lowering my FSB to 320 so the RAM runs at exactly 800Mhz, but it seems as soon as the SPD for that speed kicks in it just won't work. I can run it at FSB 319 RAM 798 no problem *shrugs*

I didn't even consider running it at 2:3 though, I might give that a whirl before I give up.

It isnt a huge deal, since it's served me well for almost a year at this speed. I just wanted to stretch this system out for a little while longer before replacing it. I'm hoping it will last me until mid next year when the prices for a nehalem based system come back down to reasonable levels

 

[wuzupfoo]

Has anyone had a problem with upgrading to Rampage BIOS with a P5B? it seemed to work but now it freezes at the logo screen.. I have tried to reset by moving the switch on the board and removing battery but it still seems to lock there.

I shouldve left well enough alone.. this board was doing fine till I got curious .....

 

[Rafael]

I do not know anyone that has done that. You are the 1st one I see.
But from my guesses there is a big chance of it not working properly, since the rampage has different chipset, more features, different sb, etc.
I think you might have to RMA your mobo or buy a new BIOS chip, and probably it will work fine again.

Regards,

Hi i am new to this forum and seeking help with my P5B deluxe board

It seems my board cant handle fsb over 310MHz! I have an e6400 (2.13GHz) C2D CPU and have been trying to OC it. I have PC6400 RAM wich shold handle 800MHz. But no matter what I do the fsb wont go over 310MHz. At 310 everything runs fine all voltage and stuff set to auto. Here you can see my BIOS settings http://www.zangenberg.net/foto/pictures/PC.jpg

If I raise fsb to 315 it wont boot and one of the fans in my PC goes to max rpm. Even if i set multiplier to 6 (default is 8) it is the excact same thing, 310 OK, 315 no post.

I am using the latest BIOS from Asus' website. Someone earlier in this thread said something about reports of this kind of error on some P5B boards. Does anyone have any ideas or comments to add?

 

[Luki]

Sounds like "FSB hole". You have to try setting it to the "round" values such as FSB 333, 366 or even better 400MHz with multiplier 6x, if OK then raise multiplier(and maybe voltage if not stable). On Intel platforms it's better to stick with 1:1(FSB:RAM) timings.

 

[pzk]

I tried 6x400 and it was the same no-post thing. I wil try 366 when I get home.

 

[Luki]

Try also weird values like 399 or 401

 

[pzk]

Are you pulling my leg?

 

[Luki]

Listen, I want to help you, if U think that I'm trying to trick you or something than OK... It's your problem, not mine ;] My E2140 is working perfectly on 8 x 400 and 1.3150V setting with 4096MB 1:1 RAM.

 

[pzk]

Sorry, I was being sarcastic. Your advise IS greatly appreciated.

 

[elconejito]

As funny as it sounds... yes, try odd FSB values. Mine is currently running at FSB 358. It will run at 359, but not 360. Go figure.

I have a spreadsheet I used when OCing my e6300. If I remember later I will see if I can dig it up and look for some values that worked for me. Also, as Luki mentioned, make sure your RAM is running 1:1

 

[pzk]

Ok, 1:1 would mean 620MHz if the fsb is at 310MHz right? I am talking about the BIOS because you dont actually select 1:1 in the settings.

 

[nicksort]

I have the same chip and the P5B board but my bios is 2001, I also have 667 ram.
I have been able to go with these settings without any problems.

365x8 w/1.28v = good start up and runs stable
375x8 w/1.28v = no start up
375x8 w/1.30v = good start up and runs stable

 

[pzk]

Just tried a couple of FSB settings with the multiplier set to 6
316-325-365-366-375-401 none of them worked.

 

[Luki]

Then try to change multiplier In my case multiplier set to 7x is only working up to FSB ~300MHz, it's quite strange cause as I said before higher multplier - 8x is working all the way up to 420MHz :/

Look at my config:

Yep, that's right. Once you've got your CPU overclocked to a good level, then you can push up ur memory if you have the room.

For example, I have mine running at FSB 358 and my RAM is running at 716. If I go up in ratio, my RAM would run at 895 (or something like that) which it can't handle. So I have no choice but to run it at 1:1. You might be in a similar boat with you're RAM.

Also (just checking since I don't know your knowledge level), did you do the typical OC stuff like disabling EIST, and whatnot?

 

[pzk]

I just tried again with the multiplier at 8 and different fsb speeds, but no luck. My screen dont even turn on and no beep or anything from the mobo.

Ehm... i am pretty noob at thin not sure what EIST is or if I have a setting for that in the BIOS?

 

[pzk]

Btw my BIOS is 1236.

Ahhhh. OK. I'd start here if I were you...

Thats the overclocking guide on this forum. It's a bit wordy, but definitely worth the time.

Hi Guys,

I've had an issue with my P5B Deluxe system for quite some time (more than a year) and I've yet to figure it out. Maybe you can help.

Whenever I first start the computer, it will fail to boot up into windows. All the fans will power up, and stay at high RPM, but no matter how long I wait, the boot will not begin. The monitor does not display anything. Period. If I keep rebooting a ridiculous number of time, eventually it will boot up. Once it boots up it works perfectly and is completely stable.

Exactly how it works is a little finicky, but lately I have been able to get it to boot up pretty reliably by:
1. Power on, and wait. I push the power button, listen to everything spin up, and leave for ~5 minutes. Variable fans stay at max RPM as best as I can tell.
2. Restart. Wait about 12 seconds.
3. Restart again. This will load windows nearly 100% of the time. However it often won't work if I didn't wait long enough in step 1. I can tell it works when the fans spin down from max RPM (this happens before the monitor displays anything, about 5 seconds after reboot)

My system:
Asus p5b deluxe
BIOS 1226
e6400 @ stock freq. (I have overclocked it before, but the reboots keep resetting it to sock frequency, so I don't bother anymore)
seasonic 430W PS
Nvidia 8800GT (upgraded from 7600 GS -- this problem occurred with this card too)
Seagate 7200.10 and 7200.11 HDD's
