Eventually overclocking is a never ending disease....!
When I was building my P4-RDRAM system (check rig) I decided (thought so anyway...) not to deal with overclocking again and stay with the more than satisfactory stock performance of my system (except the vid card ok!). But how can u leave the ASUS P4T-E without exploring its limits and trying its legendary stability??
So I went for it being quite afraid for my Willie's o/cing capabilities (didn't get the 1.6A damn!). Note that the mobo has the 600Mhz ICS-13 RDRAM clock generators and the ATX12V P4 connector plugged in with a 300WPSU. All was done in steps beginning from an easy 112FSB and RDRAM multiplier set to 3x in order to protect it past 800 Mhz as I knew I would try @133 for sure (after all stock memory bandwidth is already huge, why risk it and let the memory be my possible bottleneck even if I have Samsung RIMMs?). Next step was 120FSB where I had to raise the voltage to 1.8, 125 and eventually 133 just by bumping the voltage to 1.85. AGP and PCI buses were adjusted automatically by the mobo (now running right in spec) and I tested all frequencies while benchmarking Max Payne with the CPU demo plus Sandra's burn-in wizard for an hour-not a single crash or BSOD...! Of course it's only a 2 days o/c but I am very optimistic about it by watching the temps reach 47C maximium at heavy load (3D gaming, Sandra).
Question is how is all that possible with only an additional case cooler.... I know the ASUS can go much further rock solid but for my Wilamette, I never expected such overclockability with so "low" temps (or it isn't that low...?)! Am I just too lucky with the specific chip? I don't know its origin (Costa Rica or Malay) since I build the rig at my local retailer to give u more info....Any comments and remarks highly acceptable guys!

Nice overclock for a Willy dude That temp sounds about right to me as long as the ambient temp in your room is fairly cool. Of course evryone will suggest you run Prime95 before you call it solid but I say horse hockey! if it's stable for all your usage then it's solid Have fun and post some benchies if you get a chance.

Great O/C , sounds like you built a good rig , you may want to doublecheck your temps , they sound almost to good to be true>

i used have a 1.5 willie @ 2.0ghz too. nice easy overclock
your temps sound too good tho.
i was slammin 53C with severe case cooling.

Don't know guys...I am surprised myself too by these temps @1.85 core voltage. Note that all are read through the bios and not any monitoring utility (AsusProbe, MBM etc.)....I suppose the bios displays temps from the CPU's internal thermal diode right?
P.S: Room temperature=21C

That's awesome for a Willy!

I'm assuming that your running your benchmarks and then rebooting and checking the temp in BIOS, but temps could drop 4-5C durring that time. Use MBM5 and watch your temps from within windows, much more accurate.

Even if it's happening 51C isn't that bad is it?
Note that while trying for the 3rd day I got a random kick out of Fifa2002 while playing...No crash no nothing-just a kick in my Windows desktop-game shut down fine...Temp normal when I checked. Could it be an overclocking frenzie symptom? (Game is going reaaaally fast!)

Ok...here is the list of problems so far @133FSB...
a. Fifa2002 ALWAYS kicking me out of the game as I already said-no crash no nothing just kicks me off
b. RTCW benchmarking did the same once
c. Max Payne "got out of his body" while playing. I was watching max from away and I couldn't move him around, game playing on no crash! Awesome, ah?
d. 2 BSOD...

Note that temp never went higher than 47,5 under these circumstances and the comp is always booting nice and steady....All that reminds me of a system very close to stable but not reliable since everything else from cdwriting to internet works flawlessly...Reliability of course does count for everyone (and FIFA for me...!) so I went down to 130FSB@1.825 core voltage (that is 1950Mhz) and still testing.......
Results? FIFA didn't kick me out after playing for 30min for starters, Max Payne and RTCW benchmark fine everything seems to be in a good way!
Question is could the 3Mhz or the 0.025 diff be so crucial for whole system stability?? Calling all experts....

Ok....I think I finally got it! After running 3DMark2001 all night long (8 hours batch run) without a hinch, the former troublesome Fifa2002 for 1 hour troublefree, had not a single BSOD in general activity plus all other benchmarking games that were a bit tricky @133FSB the cpu setlled down (I think definitely) at:
1950Mhz
130Mhz FSB
Core voltage 1.825v
RDRAM 3x (turbo mode enabled) effective clock speed 790Mhz (I am 10Mhz lower..! )
AGP 1/2=65, PCI 1/4=32.5

Sandra benchmarking shows incredible results even in memory bandwidth (I 'll post soon) not to mention cpu raw performance.
Last remark is that eventually, 3 Mhz can do a difference....I strongly believe it now that I experienced it and read numerous posts for the 1.6A nwood that majority of chips is rock solid@145 but has problems @146FSB....:Q
P.S: I almost forgot! Temps right after the all night run were stuck at 47.5C!
Amazing for a Willie isn't it?

You think so my friend? I wonder since temp is almost the same at both FSBs (130&133)...How could a 5000rpm fan make the needed difference and stabilize the system? Advise plz!

P.S: For maximum stability I gave Willie 0.025v more up to 1.850 like I did in 133. Temps did not change over 48..
P.S2: I also ran Prime95 for 4 hours for starters-not a hinch! But my God this thingie really stresses the cpu- temp reached 54C after the run! Should I worry? I will give it an all night run tonight and post back

The Sandra numbers I promised:

1. CPU Arithmetic: Dhrystone ALU~ 3802
FPU~ 1021
iSSE2~ 2426
2. CPU multimedia: Integer~ 7769
Floating Point~ 9459
3. Memory Bandwidth (RDRAM 3x, 780Mhz): 2727 Mb/sec

I did....At 7 hours run it gave an error Should I back off because of it? I know I can't characterize it rock solid this way but everything else runs fine (all night 3Dmark, Sandra burn-in, gaming-benchmarking) and I need the extra power till I replace my vid card...Or should I run Prime on 1,8 Ghz and stay there if it runs ok?
Any opinions?

<< nice job!

with better cpu cooling itll go 133fsb.

>>



Question remains tho- how could a 5000rpm fan make the diff and stabilize the system@133 since temps are the same with 130 I am running now? Afterall if it's worth it, I 'll go for it...!

you will never know until you try

ThermalTake P4V 478 is only $11 +shipping at newegg - thats what i use.

the Willys are alot hotter then the Woodys - you are lucky temps are that low.
