Just received my new rig from Newegg!!

P4 Titan GA-8IHXP2
Intel 2.53 (533) SL6EV (not listed on intel's sSPEC list) Intel package date is 11/01/02
4 kingston 256 1066 rdram
ATI Radeon Pro 9700
Antec 550w

Anybody know about this new sSpec SL6EV?

well, I wouldn't mind overclocking it, but I've read alot of posts in regarding snds (sudden northwood death syndrom). Is it safe anymore? $238.00 is alot of money just to kill a processor.

Nevermind, it's a B0 stepping....just found it over at intel's website.....ahhhhhhhhh.

I have the first version of 8IHXP
and 2.53, although a different stepping.

You won't be able to o/c it too far anyway, so you might
want to do it small stepps at a time.
Try 138 FSB for CPU, run 3DMark (not for the score but to see
if it runs through), reboot check the CPU temp and then
set it to 140, and so on.

Don't worry. It won't kill the processor, since you are not gonna
go over 150 anyways :)

I just got a 2.4B B0 steeping from Newegg, pack date 10/23/02, and I can push it a hair under 3Ghz, and I think my DDR is holding me back. I'ld say that's pretty good for a B0 stepping chip :D

If you keep your actual vcore reasonable like 1.65v or less you should be fine.....It is the fragileness of the .13 gate that gets effected by the high voltage...

trust me on this guys if intel can't do 1.65v on its .13micron we are going to see alot of dead amds here shortly as I have seen many running 1.9v+ with their .13micron chips. Granted amd is starting at 1.6v but the fact is it still represents a .3v increase over that...


I am running for 6 months at same speed and 1.71v....

Also many of the SNDS I have read could easily be mobo or ram related and many are quick to jump on it. They say when I underclock it works!!! Well big deal. When you were overclocking you were overclocking the ram and the mobo chipsets, so it is a mute point. Also many don't know how to correctly identify what is the true vcore one is running at. They think what they set in the bios is gold, when in fact asus mobos like the p4b533 was vervolting as much as .08v...Ouch!!

Duvie is right about not using your BIOS to tell you what your vcore is. I have an MSI 845 Ultra-ARU and while my 2.8 Northwood is set at 1.525 Volts in BIOS, the actual vcore is 1.47 volts. (An undervolt of 0.055 volts at idle). Also, I think that the Northwoods are pretty durable as long as you don't subject them to extremes. When I built my rig back in March, I put a 1.8A in there and had it running at 1.70 volts (actual) for about eight months and it was quite stable the whole time I had it. (I finally sold it a few weeks ago to somebody here on the boards when the fan noise that was coming from the heatsink I had on it drove me to the point of insanity. I just decided to spend the money on a 2.8 and use the stock Intel heatsink/fan and sell my old 1.8A that had been running rock stable at 2.52 GHz since I got it.) The entire time I had the chip, the idle temp was around 50 degrees Centigrade with a max load temperature of around 67 degrees Centigrade. (Though the validity of those temperatures is kind of questionable due to my motherboard which seems to be reporting temperatures about 5 degrees higher than most other motherboards out there.)

So the SNDS seems to be somewhat overblown providing you don't really go crazy with the overclocking. My 1.8A overclocked just fine, and must be doing fine for its new owner otherwise he would have e-mailed me or called me to let me know. I now have a 2.8 GHz Northwood overclocked to a little under 3.0 GHz and it's running just fine. (It's about five degrees cooler on idle, and dead silent compared to my other heatsink/fan. I will probably need to get new RAM in order to try it out any higher because if I raise the fsb any higher than the 140 MHz it's at, Prime95 fails within one hour of starting it up no matter what vcore I use. At 140 MHz, Prime95 runs perfectly stable for an excess of 12 hours. I'm just not sure if I really feel like spending the 160 bucks for a 512 meg stick of PC2700 RAM for my motherboard. Oh well. I think I've gone in about forty different directions here in this post and really have no clue what I originally meant to say, so I'll just end it right here. :D )

jdurg, I have the same board and it does report temps wrong. I wonder if the motherboard is holding back your overclock? What kind of RAM are you running?


rf37, how much did you pay for that 2.533 if you don't mind me asking? A store here in town is selling that exact chip (sl6ev) and I was thinking about getting it.

The motherboard could be holding back my overclock, BlvdKing, because with my old 1.8A CPU and my current 2.8 CPU I can't get any stability above 140 MHz on the front side bus. However the RAM I'm using may very well be my limiting agent. When I bought the RAM way back in March, it was listed as "Crucial Micron PC2400 DDR RAM." However, when I've used programs like SiSoft Sandra and various other system analyzers, it's shown as Micron PC2100 RAM. So I think I may have been screwed and sold PC2100 RAM instead of the PC2400 RAM that I thought I purchased. (Don't ask my why I did that, I was new to the DDR RAM scene and building computers in general. :p ) So I have the two, 256MB sticks of RAM in there that I would like to exchange for a single 512MB stick of PC2700 RAM. I'm just not sure if I really want to spend that much money considering how I just bought a new 2.8 GHz P4.

I also believe that the motherboard temperature is wrong because as I type this right now, my CPU temperature is supposedly at 46 degrees Celsius. However, the rpms on my Intel heatsink are 0. According to every program I have on this computer that can monitor fan rpms, the fan on my heatsink is not moving at all. So apparantly the temperature of my CPU is far cooler than the 46 degrees that the motherboard is showing. (Either that or the rpm sensor of the motherboard is shot. However, it is quite cold in my room right now.)

Finally, here's another oddity I've noticed about my new 2.8 GHz P4 that perhaps could be cleared up for me. I am using the latest version of WCPUID (3.1) and when looking through some of the data for my computer, it appears as if a certain feature is supported that I'm pretty sure shouldn't be. When I open the program, I go to View->Feature Flags->Standard and open up the Standard Feature Flags window. On the far right hand side, Hyper-Threading Technology (HTT) is listed, and according to WCPUID, is supported by my CPU! Now I know my motherboard doesn't, and will never, support HTT, but what does this mean in WCPUID? Is this just a bug and should be shown as Not Supported, or is it really enabled and I'm just unable to use it because of my motherboard? If anyone else gets a chance, check that out on your system and see what it says. I'm kind of curious about that.

I was thinking that CPUID reports any C0 stepping as HT capable even though it isn't and never will be. I could be wrong though.

My MSI 845 Ultra ARU is limited to 145 FSB, with my PC2700 stick of Kingmax. I think the CPU is the bottleneck when it comes to the overclock. I thought about wire tricking it to 1.85 vcore, but I think that's too much to get something out of the CPU that I probably won't even notice. I am left running my 1.6A at 2.26 GHz until I get the cajones to wire trick more and stop caring about the longevity of the CPU....
