New rig alert: 2.4B@3492 + P4G8X

I've seen too many AMD threads in this forum lately, thought I'd add a little spice to liven things up😉.

Before I begin on the multiday benchfest, I'm going to give my first impressions about the new rig. Firstly, the responsiveness of this chipset truly has to be seen to be believed! I recently was lucky enough to have a P4m cpu in my P4B533 running with rock-stability at 225 fsb, which yielded swifter response to tasks such as opening windows and apps, the type of tasks whose timing you become familiar with over time. This board blow that away, IMHO. Task initiation has become as near to instantaneous as I've ever seen, on any rig. Set up (yes, it's a clean install of WindowsXP Pro) was a breeze, no hiccups or surprises along the way; I was already familiar with the "installing the USB2.0 QFE fix and the USB driver before rebooting" issue from the P4B533 board driver installation, so that wasn't a problem. I was a little worried about the Vdimm only going to 2.7V, but then I realized that my mem would have to be running well in excess of 200fsb for that to be an issue, so no sweat there either. The dreaded Asus overvolting is evident in AsusProbe again, more than ever🙁. Funny thing is, though, that where the overvolting was consistent on my P4B533's bios and Probe, the P4G8X bios says 1.525V Vcore and Probe says 1.613V. Strange. . .I may end up installing Motherboard Monitor later on to see if the in-OS readings are consistent.

Without further ado, here are the "new and improved" specs for my rig du jour:

Pentium 4 2.4B, SL6EF, C1 stepping, week 39
Asus P4G8X, E7205 chipset (AKA: Granite Bay), 1003 BIOS
2 x 512MB (1024MB total) Corsair XMS3200C2, 2-2-2-5 bios/2.5-3-3 actual (???)
ATI Radeon 9700 Professional, 380/336(core/mem)
Philips Acoustic Edge
Western Digital WD800JB, 80GB, 8MB cache
Maxtor 6Y060L0, 60GB, 2MB cache
homemade H2O cooling system

Edit: I have found borderline instability (AGP-related) at 175fsb+ but have eliminated this issue by increasing the Vagp to 1.7V😀😀😀!!!

 
cant wait to see these results 🙂

only 1 Q for ya ~ do the cas timings work when overclocked?

dont worry bout the overvolting~
that would mean youll fry your cpu when idle? ...but if you placed it under load it would be ok cause the vcore drops? im not buying that no more 😉

what, are you nuts:Q😀:Q??? next, you'll be waiting to see my results after "burn in"😛😉😛.

good looking on the actual CAS settings when overclocked😉. how did you know about that? I hadn't read that anywhere. I wonder if the mem timings automatically default to SPD at higher speeds, which is fine since I've got a pair of XMS3200LL sticks on the way this week😀.



Looks to me like I've found the ceiling of the cpu at default Vcore pretty quickly, gonna bump the voltage and be back later🙂. . .

 
The Vcore drops by design on P4's as the Icore (current) goes up, so it's a moving target regardless. At 80% load the VCore should drop about 0.15V below its idle voltage, according to table 2-7 of Intel's info here.

nope ~ it defaults to 2.5-3-3-7 (not spd)

that's just like you, THUGS; snatching away my hopes with the blinding light of facts and reason😛! There has to be a way around this, as the Sandra screenies on the |H| show, Kyle & co. were able to bench the mem at 1.5-2-2 timings. Perhaps an earlier bios? We'll see. . .in the meantime, I've got Radeon issues

My Radeon Pro has been giving me balls.I was getting Infinite Loop after running 3D with overclocking my CPU.Sometimes it would freeze on the Nature test or I could hear my hard drive making a light funny noise.When I hear that I know something might happen and get the infinite loop.If I did get through it there was a chance it would not boot back to windows,reformat🙁.I tried adding 1.6V agp but never tried 1.7V agp.The 9700 Pro don't like being overclocked.I didn't bother OCing the video card.I tried almost everything other than take the hammer to my system🙂.I run a 8RDA+ and 2100+ Tbred with the Pro.My mobo is locked automatically at 33 pci and you can set the agp to 66 or higher and even lower to 50,but that seems to do nothing locked at 66.
 
Man I just saw several OEM tray C1 stepping P4 2.4B's at Pcclub today, man was it hard for me to avoid getting one!🙂
 
Thanks for all the info/props, guys🙂.

I think that I'm about at the top of this cpu's headroom, since it failed P95 in 15 minutes at 3510MHz, but I will be attempting to hack the memory timings via WPCRedit tonight, so stay tuned😉.
