2.5v on the DDR2 is insane. You need to watercool them, and even then, they should die in few monthsQuote:

Well, here's my rock stable overclock, vNB 1.45 and vFSB 1.40, 5-4-4-15-4 timings. It is also 8h Prime95 small FFT stable
I post OCCT RAM stability, as it is impressive on those settings for the P965. Even the X38 has a hard time to do it on 266 strap

I should have wrote that my DDR2 is at 2.05v It is just a little warm to the touch. I have been overclocking memory for about 9 years now and never destroyed a module on air yet. I have run DDR2 up to 2.3 with no problems. If memory gets to warm, you will start getting memory errors. It is not uncommon to see the Max operating temperature specifications of DDR2 at 85c. I have even seen it has high as 95c max.Quote:

Probably not the place to post but has anyone tried an E8400/E8500 on one of these boards? I'm curious to see if these boards will do 500FSB+ without too much hassle.
I run a FSB at 1680MHz. You must be talking about the Dram Frequency. That changes with the CPU frequency and the multiplier. For Example. I have my CPU Frequency with a multiplier of 8x 420 Mhz CPU Frequency at 1:1. I have and the dram frequency is 420x2 - 840Mhz. I also have the options to set it at 1050MHz, 1260, 1400, 1680. I keep it at 1:1 because my memory will not rum much higher. So I have a 8x multiplier because I get a greater CPU and FSB than I can run a my default of 9x.Quote:

For every day use, I enable the C1 function. It seems to work the same way as SpeedStep. SpeedStep is not an option for me because it is disabled when I changed the multiplier. Why would the board have both options? If you keep the multiplier at default, you can enable both SpeedStep and C1 (enhanced Halt State) Would they both work together or would one take control and disable the other?
What about the TM Function? How does that work? Does it just allow the CPU to throttle down we it is over heated? Or, does it work with other power management functions?
Peg Link, When I first had this board, I destroyed a Video Card by setting it at fast. At least I think that is what happened. (I was going to get a new one anyway) Does anyone set it at anything but Auto?
EIST and C1E sure appear to be the same thing, but they are not.
EIST handles the FID (Frequency ID) of the CPU, which means it's responsible for lowering and increasing the CPU frequency on-demand or by software request. Also, keep in mind that you EIST might still be enabled when you select a FID on the BIOS. You might just be selecting the MAXIMUM FID available for the CPU, not locking it.
CxE handles the VID (Voltage ID) of the CPU, which means it's responsible for controlling the CPU voltage, especially if the CPU enters idle mode. Also, CxE handles the enhanced power savings modes of the CPU. It may just be lowering the VID when the CPU is idle and at minimum FID (C1E) on desktop CPUs, all the way to lowering the FSB and voltage, along with an enhanced CPU power-down (Hard C4E), on some T7x00 and Penryn mobile CPUs.
The TM Function does in fact handle the CPU throttling (and shut down) when it's overheating (though you can force those states through software, too). If I remember correctly, TM1 is embedded on all socket 775 CPUs and can't be disabled; TM2 (enhanced version, which not only forces throttling but also a CPU VID and FID) can be disabled, though it's usually enabled. Since they are preventive measures, and don't kick in unless REALLY necessary, I'd advise you not to mess with TM, unless if you want to set a lower default VID/FID for TM2, which could be beneficial.
As for PEG Link, I never had any problems with that, even on fast settings, other than an occasional system hang. I've also not seen any noticeable performance boosts when using it, though...
Cheers.

I have the C1 enabled. My Core Voltage and FSB does not seem to change. The only change I can see with the assorted utilities is the multiplier from 8x to 6x.
Could you please explain how the frequency ID is involved it the process. I did not get that. I looked at a couple Intel pages and did not fully understand that either.
Are you saying that I should disable the TM function in the bios? And why should I do that.
I am trying to get some knowledge with this whole thing but get lost in some of the terminology.
Thanks a bunch !!!! jonny_ftm :) I am going to run the RAM test set as you have it tonight.Quote:

Nah you misinterpreted my question. :)
I just want to find out if anyone who has bought the new E8400 has tried overclocking it on one of these 'old' P965 chipsets. My old E6400 is starting to show its age with its lowly 2MB of cache & I'd like to try some testing with one of the newer 6MB 1.2v CPUs, as they are easily hitting 4GHz on air, even with stock cooling.
The plan is to try 444x9.0 for 4GHz @ reasonable volts, then try for 500x8 1:1, then aim for the FSB ceiling by dropping the multi even further. The RAM (in my sig below) does 1013MHz+, so if the mobo can handle it, I hope to gain 2000FSB with either the rev 1.04 or my unused rev 1.10 P5B Dlx.
The question is, can they handle this kind of abuse without mods?

That's just monstrous Dinos! Thankyou for posting up a screenie. :up:
You've convinced me to pickup a new CPU on the weekend. Hopefully these Patriots will do the job, as I haven't been able to push them to the brink yet. :)
Are there any VDroop, MCH mods done on that board? I'd assume you've done them all?
that was his overclock not mine
i am going to receive that CPU and another one in a few days depending on my :banana::banana::banana::banana:ing useless courier company lol
i also have that board but i run it all stock :D
Any idea whether P5B dlx is able to run wolfdale ?
I'd love to switch to one of those E8x00- ~4ghz is veeery tempting :D
But having to change motheboard- sucks...
Anyone managed to run any of those e8x00 on p5b deluxe ?
I run it on my P5B-D no problem. check it out hereQuote:

Hi Guys,
Dino22 bought that CPU off me, however please, for people with P5B-Deluxe, see this thread:
http://www.xtremesystems.org/forums/...d.php?t=174145
c'mon P5B-Deluxe owners. Overclock your e8400's to 590 fsbs, there have got to be another person who can do it:horse: :p:
Surely, I can't be the only one.......

If you have one that's no longer used, pull it out and give it a test :D
Ok, first of all, sorry for the delay. The XS auto-notification feature again failed to notify me of yet another reply to a topic I had subscribed... go figure...Quote:

EIST - Enhanced Intel SpeedStep - handles the FID, also known as "multiplier", "multi", and such. On EIST-enabled P4s, minimum FID is 14; on Core-based CPUs (except single-core celerons, which don't have EIST), minimum FID is 6
CxE - C1E for desktops, up to Hard C4E for laptops - handles the VID, or voltage. On SLFM (Super Low Frequency Mode), only available on selected laptop parts as of today, this can be as low as 0,85v, via software (though you can go even lower on some desktop motherboards). Every Core-based CPU has CxE enabled, and that is what makes the things so messy for the "casual looker", as you'll see below
TM/TM2 - Thermal Module - they (all Core-based CPUs have both, as some P4s; every P4 has at least TM) handle how the CPU reacts when overheating (that is why you should keep them ON); TM just induces wait states on the CPU (forced idle periods, up to 87,5% of the CPU cicles), allowing it to continue operating, just at reduced performance, when overheating. The 3.8GHz EE P4 was the only CPU up to this day that, even at stock, triggered TM for some period of time :rolleyes: ; TM2, on the other hand, and because TM has its disadvantages (like "drunk" mouse pointers, and such), activates a special CxE function: it lowers the operating voltage AND multiplier (see, I told you it would be messy) to the minimum allowed for the CPU, cooling it faster and with less drawbacks in terms of software "hickups". Since TM2 appeared, TM became almost obsolete. It will still work, but only in EXTREME circumstances. In short, leave these two on, unless you have VERY specific reasons to disable them!
[EDIT]Ups, sorry. Forgot about one thing: RMClock can in fact manipulate the TM2 settings: you can change the FID/VID for the TM2 function, or even disable it. That's why you couldn't get that part (sorry, I was assuming too much). While I wouldn't advise you to disable TM2, you can make it even more efective, but that's for a FID/VID manipulation class, not this one... hehehe [/EDIT]
So, now that we have that out of the way, let me tell you how this "mix-and-match" works:
When left alone, usually EIST, CxE and TM functions are enabled (if the CPU supports them), working like this:
1) EIST handles the multiplier according to driver instructions on the CPU load (which is why you can force a FID on Windows, be it minimum, maximum, or in-between - but for "in-between" ones you need something like RMClock);
2) Since lower FIDs usually don't need the same voltage as higher FIDs, CxE handles the VID for those FIDs (also changeable via RMClock), and, in case of laptop parts, it also tells the CPU what to do when idling (like powering down some parts of it);
3) In case of overheating, TM2 (if available) forces the 6x/14x multi, and minimum VID; else, TM forces idle CPU cicles; when the CPU stops overheating, TM/TM2 disable themselves and the CPU resumes standard operation.
Now, for EIST-disabled but CxE-enabled CPUs (2xx and 4xx Celeron CPUs), you'll have at least two FIDs: 6x/14x and the maximum FID. This is by design, the 6x FID is for CxE operation. The good thing is, software like RMClock can also force the 6x/14x FID by software, which is why this can be SOOO messed up... Intel could just EIST-enable all CPUs and be done with it... They have to take an extra step to disable all but the minimum and maximum FIDs...
The weirdest thing of all is BIOS-manipulated FID selection. If you only tell the BIOS the FID/multi you want, CxE and EIST will still be enabled, meaning you will still have the power-saving features. Which usually is a good thing, unless you OC.
If you OC, the CPU power requirements go up (no news there :p:). Starting somewhere, the minimum VID for the lowest FID allowed for your CPU with EIST/CxE enabled is not enough to the OC you want, resulting in a no-POST situation. Starting there, it will probably be a good thing to disable CxE (TM2 can still probably lower the FID, so you'll still be somewhat protected).
At this point, let me tell you that, unless your OC is of such magnitude that simply changing the FID can cause disturbances (not that likely, I think), you'll might want to keep EIST enabled. If you need to benchmark, and there the FID changes WILL make a difference, you simply need to change the power scheme in Windows before the benchmark to "Max Performance".
So, there you have it. Pretty much all what I managed to learn about EIST/CxE and such over the last few years. I've had plenty of experience with FID/VID manipulation by software (RMClock rules! :D), so at least that part I know it's fine (though it may lack somethings, I don't want to kill anyone of boredom... hehehe); the OC parts, referr to my usual disclaimer :p:
Cheers.

I have a video problem, when i go past 430 FSB i lose more than 50% perfomance in 3D, i go from 200 fps in hl2 dm to 30-40 fps. I dont know how to resolve this, i read that its the pci-express to goes from 14x to 1x , but i put it on 101 mhz and i tried more values and i have the same problem, wtf!! I tested my pc with memtest, orthos prime for hours and hours in everything and its stable! and when i go to play hl2 or hl2dm in the first screen of the presentation of the game i have sound corruption. i also read that my memory can cause this because OCZ and Asus are not friends lol. What do you think?
PD: i tried to put the max voltages in the chipsets, fsb etc etc and the same problem. My card is 8800GTS 320 and its OC but i tested it with Atitool and its fine!
try 96MHz for PCI-E, it works for meQuote:
