WHAT'S THE HIGHEST NW "B" CPU KNOWN TO WORK STABLE WIth ASUS P$T-E?

[JAS_abx]

Hello all!

Thanks to PCBruiser for letting me know I had posted in the wrong place so here goes again....

I am not into OC as a rule however my intentions are to use a NW"B" on my P4T-E rather chan an actual o/c. The only thing I'd be doing is raising the FSB to 133 to match cpu. Looking at a 2.8 or 3.0G cpu.

I'm new to the forums and have joined b/c I have a few questions that's been left unanswered for some time.

- What's the highest NW known to work stable with this board?

The board in my machine is utalizing the ICS chips so there shouldn't be much of a prob. I have 3 more P4T-E's that I picked up for a song and dance. However the remaining boards have the CYP CG's. Initally I was going to build a couple of systems and sell them and keep the remaining board as backup. Thought of backing up my vinyl onto a system and maybe X-fering them to cd. May even build a server to play with being I could use hands on when it comes to networking. Hi!

My next question is regarding the CYP based gens. Being that is most likely hood these won't clock at 133fsb, wouldn't they still perform much better than say the "A" Northwood? The chips are cheaper and here in Canada, probably most places, the "A's" are becoming more difficult to find. At the moment the boards are setting here until I can come up the the $ to build the other systems. Could have purchased a couple of "A's" but would much rather wait to get the "B's".

Any input would be greatly appreciaced. TNX in advance.

The fastest Northwood B that I ever ran on my P4T-E was the 2.53Ghz chip - this ran without a single problem.
I had it combined with Kingston PC1066 RDRAM and it was 100% stable.
The 2.8Ghz Northwood B (couldn't remember if there was one or not) but if there is one that should be fine too.
Above that you've only got the 3.06Ghz Northwood B.

The problem here is that this CPU was the first one to have HT built in and enabled.
Now the P4T-E will give you no HT support - there are no BIOS updates to enable HT, there aren't for any 850 based motherboard.
Now in theory there should be no problem, the 3.06Ghz CPU should run without HT being recognised.
However after a couple of people read through my guide on how to install a Northwood B into a P4T-E:

http://www.cifi.com/computing/p4teoverclock.html

They e-mailed me to say they were having stability issues with that combination.
One person promised me he had an ICS equipped board and was using PC1066 RDRAM but was getting crashing issues.
Unfortunately my P4T-E was passed on before I was able to try it with a 3.06Ghz CPU so I cannot confirm/deny all of this.

To be 100% safe then source 2.8Ghz Northwood B's - these are identical to the 2.53Ghz Northwood B's that I tried, with the exception of a higher multiplyer.
The 3.06Ghz Northwood B is a slightly different animal and from what people are telling me there maybe problems.

The CYP equipped P4T-E's are not too happy at 133Mhz FSB (533Mhz) - it is definitely a clock gen issue as even with PC1066 RDRAM they have stability issues.
The best you can really expect from them (and remain reliable) is around 120Mhz FSB.
However because your Northwood B's are locked then there will be a drop in performance.
Examples:

2.53Ghz Northwood B - on 120Mhz FSB this would run at 2.28Ghz
2.8Ghz Northwoob B - on 120Mhz FSB this would run at 2.5Ghz

Hello! BladeRunner, thank you very much for the info. You gave the answer I was looking for. I've been thinking about the purchase of either a 2.8 or 3.06G processors. Mor on the 2.8G b/c I was curious about the later working on this board.

When I built my system a little over a year ago it was a big decision BT this unit and the P4T533 variants. Decided on the P4T-E after a friend was telling me how stable it is. He had the originaly P4T -->P4T-E. Rather stability over speed any day. Therefore I went with the T-E.

Again, thank you for the input. A 2.8B it'll be.

As a note, one other interesting thing I learnt from the forum is that these boards can utalize PC1066 RIMMS.

Next time I have my P4T-E up, I will try a 3.06 and run ME or Win98SE, they don't support HT anyway. I would think it would work.

The Iwill P4R533 board supports HT with a BIOS update, as does the P4T533-C. I always forget but maybe because these are Intel 850E boards? I forget which boards are 850 or 850E.

If your board has the Cypress chips run 3x on the RDRAM. The Cypress CRCGs are pretty bad, worse than the ICS-09s. Some CGs may only be good for 112-115/4x. So you can run maybe 149-153 fsb/3x.

This thread is a little stale, but I find myself in the same scenario. Will a Pentium 4 3.06GHz 533MHz FSB Northwood processor run on the Asus P4T-E motherboard?

Clevor: Did you succeed?

BladeRunner: Any tips? I've read your webpage, very helpful. Should I only go for a 2.8?

I currently run WinXP Pro SP2 on a P4 2.0GHz 400MHz FSB. My memory is Samsung PC-800 RDRAM (2x256). This system has been rock stable. I've got the information on the jumper settings - no sweat. I've read just about all the P4T-E threads here on the forums.

Just need to know which Northwood to upgrade with, can I use the 3.06?

Thanks!

According to Asus support-page which shows CPUs supported by
different MB:s, the highest supported CPUs for P4T-E are Celeron 2.8 GHz and P4 2.6 GHz.

I have my P4T-E very finely tuned right now, so I'm afraid to tamper with it. I don't use it much and currently have it set up with an X800XT PE for gaming.

I last ran it two weeks ago to exercise it: ran 3DMark2001/2003/2005, Aquamark, GhostRecon, PCMark2004 Pro, SS2nd Encounter and IL-2 demo loop for 30', CodeCreatures, UT2003 bench, GunMetal demos, SuperPI 16M, all at 1600x1200x32, 4xFSAA, 16xAniso. Just rock stable with a 2.0A at default volts (1.48 actual!), maxed out at 156/4x with 2x256 Kingston PC1066. Just amazing how stable the board is and how it makes the most of VCORE to the CPU.

So no, I've not tried the 3.06B. I am 99.99% sure it won't work. When I ran the CPU on the Iwill 850E with improper BIOS, everything was in slow mo until I flashed to the BIOS that supports HT.

You cannot run a bigger CPU or faster system on the P4T-E: 2.0A maxed at 156 fsb for 3.16 gig. But didn't Intel make a 2.80A? Not sure.

But the rig with an ATI PE will handle anything in gaming except Doom3 at Ultra detail. Far Cry at 1600x1200x32 runs fine at ultra detail with a PE, as well as HitMan Contracts at 1600x1200x32 and with postfilter to MAX!

The only potential problem is the HT.
There is no HT BIOS for this motherboard, so simply put there is no support for it.
However there is plenty of voltage there for any of the Northwood B CPU's and as the ONLY Northwood B CPU that ever had HT was the 3.06Ghz you should be safe with any of them up to this speed.
Of course I cannot guarantee this at all, however the Northwood B 2.8Ghz is in theory the last 99.9% chance of success CPU.
There shouldn't be an issue with the 3.06Ghz - however the fact it does have HT enabled onboard and the P4T-E itself doesn't may cause some issues.

I'd say to be very safe go for a NW "B" at 2.8Ghz combined with some PC1066 RDRAM.
The only thing you're overclocking with such a setup is the 850 chipset which I know is more than stable at 133Mhz FSB so long as you're using those ISC clock-gens.

Thanks for the tips / advice.

I do have the ICS chips. Sounds like 2.8 is the right choice for balancing the increase in performance versus the risk. Good pts about the HT, only the 3.06 has this issue.

Great information on this forum.

Thanks Clevor and BladeRunner!
