PD 805 winging its way to me..

[Arthalen]

Well fella's, I've just done the dirty deal and this is winging its way to me now...

Pentium D 805
Asus P5WD2 Motherboard
2GB (2x1GB) Corsair Value Select DDR2 533
Thermaltake Big Typhoon HSF Cooler
Artic Silver 5 Paste
SilverStone FM121 Fan (110CFM!)
HiperPower 580Watt PSU

Along with what I have already:

Thermaltake Soprano Case
Asus Geforce 6600
2x WD 40GB HDD
DVD-Rom & CD-Writer

Wish me luck - this is by far the biggest overclocking project, and the riskiest, I've ever attempted. I'll post updates and news as I go along (if anybody is interested!)

AIM: To hit 4ghz, but I'll settle for 3.6!

 

[Arthalen]

Anyone had anyluck with changing the fan on the Tt BT at all ? I was going to go a little crazy and but the Fan above on it for some real HC air cooling...

 

[Arthalen]

Well, I'm glad to say the parts have all arrived nice and safe, so I'll sign off now and wish me luck ! First LGA 775 system I've put together

 

[Arthalen]

Well, im sitting here very happy -

All the parts have arrived on time.
PC is now fully built.

PC is working Great!

To say I'm a little relieved is an understatement, as although I've built plenty of K7 PC's and a couple of P3 and K8 PC's, this is the first time I've dealt with LGA775. Not only that, the Thermaltake Big Typhoon WAS A NIGHTMARE to install. I had to even get the sandpaper out for the brack to fit in in correctly!

The motherboard seems to be a superb peice of kit, very nicely designed and laid out, and the PSU I've puchased is excellant. Even has the new fangled 8pin attachment that the motherboard likes

For the record, on starting this little project:

CPU Temp in BIOS at 2.6Ghz: 43C
MB Temp in BIOS at 2.6Ghz: 30C
Vcore is steady at 1.3V ... plenty of room to clock with methinks!

Yet to start the overclocking with this thing, I'm just gonna flash it to the latest BIOS and get windows installed.

Hopefully, once Windows is on I'll post a few Pics.

 

[Arthalen]

Nahh, its an all or nothing deal for oc dual cores I belive.

Anyways, got windows on last night, sorted out a few programs and all my drivers and SP 2 this morning.

Got Dual Priming going at the moment to test temps and were stable at 52C at full 100% load on both cores. Not bad.

Good news - Rightmark is telling me that required Vcore of rthe chip is only 1.275, and its currently at 1.3vcore at idle, so I should have some room to overclock this afternoon.

Bad News - Super Pi score is disgusting ... 49 seconds.... admittedly I've dropped the mem down to DDR2 400 and loosened the timings a lot as It'll be the bus I want to push the most.

any other Benchmarks I can do to see a baseline performance before I go off OC'ing ???

Cheers,

 

[Arthalen]

Good luck, that seems quite a high temp just for stock but thats dual core I guess. Is it possible to just overclock one core and keep the other stock for those multitask things

Thats a Smithfield core for you, unfortunately. Its nothing to worry about at this stage, Im hoping my Big Typhoon will improve in its performance as I push it more up and up (*gulp* I hope).

Prime Update: All good, nice and stable at 53C, no throttling, no vcore variations and Case/motherboard temp is stable.

Looking forward to turning this thing up this afternoon!

 

[Arthalen]

Raikiri: Oooh of course - lol remember Aquamark 3 from when I was benching a 9600 Pro lol.

Off to get the baselines now.

 

[Arthalen]

Baseline Performance:

AquaMark 3 33,662 (GFX: 4305 - CPU: 7712)
3DMark 2001SE 12,102

Hmm, not the best in the world, but then I knew the Video card isn't the best in the world.

Have to see how much this Thing can go up

 

[Arthalen]

Okay, step one is fine - FSB Set at 144mhz, running at 2.88Ghz and no issues. Stable for an hour and temperatures are still normal, really.

Infact they've dropped a bit. Could be that the AS5 I've used has cured properly.. weird.

Time to go higher...

 

[Arthalen]

nicely, just out of interest what cpu did u have b4 the 805?

Me? I had a Sempron 2600 on a Skt 754 Asus K8N4-E Deluxe mobo. Pushed it from 1.6Ghz to 2.3Ghz on stock volts to Vcore as the motherboard didn't support the option!

 

[Arthalen]

Okay, a few more steps up the ladder....

Settings that havent changed:

Memory
Using a divider that keep sit below DDR2-533 Mhz, timings at SPD.

Locks:
PCI-E Locked at 100 Mhz
PCI locked at 33Mhz

Volts:
All at stock voltage so far.

So Far:
FSB 144 - 2.88Ghz - Stable - IDLE 38-40C LOAD 54C - No Throttle
FSB 155 - 3.10Ghz - Stable - IDLE 38-40C LOAD 58C - No Throttle
...and...
FSB 166 - 3.32Ghz - Stable - IDLE 38-40C LOAD 58C - No Throttle

** Bench at FSB 166 - Super Pi now down to 40 seconds, 20% improvement! **

Impressions: So far, so good, voltages have remained at stock and are not fluctuating, temperatures are remaining at normal, no issues with boots or BIOS. Everything going well so far.

The coolest thing about all this ? Even while Dual Priming this system is running extremely fast, extremely responsive!

 

[Arthalen]

Just booted into windows at 180 FSB - 3.60Ghz!!!!

Idle Temp - 45C ..
Load Temp - 65/66C .... :/

Vcore - 1.3375 Volts

Hrmm, I might have gone 0.0125 or two too muc hwith the voltage may be able to knock it back down if things prove stable... I'm still in the early stages with this, but glad I've managed to reach 3.6Ghz so far

I am wondering if my thermal monitor is misreporting the temp however - PC Probe 2 ... any others out there that work with the Asus P5WD2 ?

The Stress Prime 2004 really is b**chin my system up to say the least to test it ...

Anyways, back to considering the next step...

 

[Arthalen]

status: FSB 180Mhz - 3.6Ghz.

This is getting a little weird now. This thing has run Prime stable for 1 hour now with no glitches or problems. Been browsing the web all this time and doing a little word processing.

However, PC Probe 2 is saying I have a loaded temp of 69/70C on the CPU, and this is confirmed by Speedfan which is saying 69/58C for each of the cores.

I've taken the side of the case off, and had a good feel around. Plenty of air flow coming into and out of the case. I have a Stilverstone FM 121 pulling in cold air and its doing a good job of it.

The Big Typhoon, although warm, is not burning hot. I felt around the fins, the heatpipes, and the copper base - warm yes, but not burning hot. I ve tried pushing the BT down incase I've installed it wrong and its not making proper contact, but the temps didn't budge. This is leading me to believe its doings its job properly. AS5 was applied as instructed on the website.

Case/MB temperature seems ok for what I'm doing - 35-37C.....

Rightmark is not showing any signs of real throttling, so the CPU seems to be thinking its ok...

Could the temp sensor report be wrong ?
According to CPUZ its a Winbond W83627EHF.

Now that I've killed off Dual priming, and let is rest back to idle, I have IDLE temps of 45/46C.

Benchmark at 3.6Ghz: Super Pi - 37.4s !

 

[Arthalen]

Theres no way that a big typhoon would be having temps like that, and as its not a bracket instalation I cant really see how you could have installed it wrong, which leads me to believe the temp sensor has to be reporting incorrectly. What bios are you running?

Im running with the latest BIOS Update to properly recognise the Pentium D 805.
Bios Ver: 0501

The previous BIOS version was released before the 805 was released...

Admittedly, I haven't updated the PC Probe (which reports a single 69/70C), but then Speed fan was reporting 69/70C on one core and 58C on the other.

I'm gonna nip out on Dinner back to the shop where I picked up the Big T, and check out the other ones to see if there is any issue between mine and the other ones they have.

 

[Arthalen]

Question: Would an extra 120mm fan blowing at the copper base of the BigT help improve it ? Or is this going to interfere with the Heatpipe system ?

I'm thinking of the following:

1) Download the latest PC Probe and double check my temperatures... if the same then:

2) Remove the BigT, replace the Stock Fan with my SilverStone at full pelt. If the missus gets annoyed with the noise, I'll tell her I need the cash for some watercooling.

3) Remount the Big Typhoon, take my time over it and make sure its secure on the chip.

4) Mount the original 120mm fan into the front of the case, and then use the spare BigT fan to cool the copper base of the BigT.

Get it back in the case and get it tested again.

Also, need a suggestion for removing AS5.. don't have any TIM Clean available at present.

 

[Arthalen]

Something is defiantly wrong with the temps, I wouldnt imagine replacing the fan would sort it out as when I had a BT on a Intel at 1.675volts it never went over 40c.

I would say that updating the PC Probe should be your first bet, I dont know what the software is like but if its anything like Abits Uguru then it takes over the sensors and interfers with speedfan and motherboard monitor.

Also I just use a tissue to remove AS5, does the job for me

Which chip did you have the BigT on ?

 

[Arthalen]

Ok back at home, time to burn this sucker some more.

I've just booted into windows, and exited the PC Probe I have installed.

Run Speedfan, let the temps stabilize, and this is what I have:

Temp1: 31C
Temp2: 41C
Temp3: 17C

If I run PC Probe now, they are the same. Hrmm. I've d/l the latest PC PRobe 2, still the same (pretty sure its the same proggy, actually).

Although the software is telling me the same, I'm not 100% convinced. 1) is that the temperature 'twitches' a lot when loading stuff by upto 5C before settling back down again and 2) I've read a lot of reports about the P5WD* range having temperature reporting issues.

I'm going to run a few tests and see if I can deduce anything further.
