Am I safe??? (And does this Duron kick @$$ or what?)

[jimmypop]

Here's the rig I am running right now. I am a bit new to overclocking and so I want to verify that I won't burn my system up too bad by running at these speeds:

Abit Kt7a Raid
Duron 750 @ 962 (6.5*148)
128 mb Kingmax PC150 (at CL2, not sure what it's rated)
AIW Radeon
Quantum AS 30gig ATA100 7200
Ensoniq PCI sound
Linksys NIC
8x Raite DVD
8x4x32 Iomega CDR

oh yeah, fans...those help . In my generic Electroseller.com case, I've got two intakes, one directly over the CPU off the PS (running an open case until I have the time to mod it), one in from the front bottom (these two are 80mm, btw), a blower in the slot 2 slots below the AIW Radeon, an old cpu fan (40mm) going out the back above the PCI slots, and a Chrome Orb, with a little layer of the thermal grease I got from KD Computers (It's white, if that matters).

Yes, I know Chrome Orbs suck, but I didn't know that when I bought one. Looked cool . My temps vary from 25C idle to about 45-46C under a load. Is this just too hot for a Duron 750? Looking to go to another HSF, but only have about $25 to spend, shipped...any suggestions?

I can POST at 11*100=1100, 8*135=1080, 7.5x142=1065, and 7*148=1036, which I find unreal. However, the temps are much too hot and it goes kerplunk fairly quickly. Haven't tried to keep it at much more than 962 6.5x148(rock solid 12 hr loop with sandra stress), I've run at 975 (150 fsb) and that seems ok, but I don't trust it there...however, the Sandra scores of 610/720 are UNREAL .

My Vcore is set 1.85 in BIOS, reported at 1.9. My VIO needs to be set at 3.7 to be stable at 962, reported at 3.59. Is this VIO too much? I don't want to fry Hawk's nice new RADEON AIW (this card kicks ass, BTW)

Thanks for your input!

i had the same question as well - will going to 1.85V on my duron @ 900 fry it eventually? it runs idle at 29C and 46C under a full load. at 850mhz, (8.5x100) the chip only needs to be set in the bios at 1.725 for everything to be running smoothly.

for some reason i can't see the 50 extra mhz demanding that much Voltage in order to remain perfectly stable.

btw, to test stability i run Prime95 under the 'torture test' option. it's a great way to test how much voltage you need on a processor.

If you can post at 1080 with the chrome-orb, another heatsink will probably be stable there.

PLYCON has a grea8t deal on the HEDGEHOG $38 ! Spend the few extra $
and get yourself the best heatsink on the market!

 

[jimmypop]

Yeah, don't worry, I am looking into a new HSF . I need it desperately! Anyhow, can someone tell me if 3.7v I/O is too high? Is that risking hte Radeon AIW or anything else? Thanks!

 

[jimmypop]

Scares me to think that a $60 processor can challenge Intel's P4 in business apps .

 

[Asha'man]

hmm when running under full load (RC5) with my duron I get slightly higher temps than that....around 60 degrees C...

duron 650@1000 right now, using the not so good s-ORB. Looking around for watercooling though. also, running @ 1.85V reported 1.9V

Hopefully it won't burn waiting for watercooling

[Miraluka]

Why don't you have the front bottom fan sucking air into the case, and the one fan at the back by the cpu blowing air out of the case? That is how I would do it.

 

[JustStarting]

nerdsbyte has the Taisol CGK742092 w/ a YSTech 25mm fan for $27.99. My CPU rarely approaches 35C after an hour of UT. I have an Antec SX1030 case and it is awesome for cooling an OC'd CPU. My system temps are 22C. 10C- 12C over system temp is typical for an OC'd CPU

 

[jimmypop]

front bottom in this case is a little blocked, so i have it at about a 45 degree angle blowing in. might have to check into that hsf mentioned above, although i dont really have the $ for it .

 

[jimmypop]

i think my cpu temps are lower than yours since i have quite a bit of air moving around in the case, which could throw the readings off a little. i recalibrated them today (checked the sys. ambient and northbridge at 500mhz) and it looks like i'm running closer to 54-55C. Suck :Þ. Oh well.

 

[jimmypop]

any other ideas?

 

[kw3i]

DOH i spent 49 on it+delta just last week, oh well, whats 5 bux in 2000

I run a Duron 700 stable at 1083MHz (10.5*103) on a KT7 mobo. I use a CoolerMaster Case is a modded Enlight 7237 DP5-6H11 HSF. CPU temps: 38C idle, 44C full load. See "His Rig" for more info about my setup.

 

[Quaggoth]

Yeah dan, That's what I'm talkin about. I run a 700@981@1.725V@44C(111F) (109X9)
I use a cooler master as well. Will be faster. Memory is PC100

Picked up the GlobalWin FOP32-1 from KD Computer for $25.60 including s&h. If you go with this one, be sure to remove the thermal pad and sand down the area in contact with the core. Bottom of the heatsink is pretty rough. I started with 180 grit sandpaper, then 220, then 800, then finished with 2000 (Found the 800 and 2000 in the automotive section at Wallyworld). She be extra smooth now.
Also be sure to use good thermal compound (eg. arctic silver). My cpu temp dropped about 4-5C after this mod compared to the unsanded hsf and stock thermal pad. Reported temp from my KT7A-RAID is 32-33C and 24-25C case @ idle.

Duron 650 @ 891/137. Just cruisin'. Will run @ 910/140 and boot windows at 945/145.

 

[jimmypop]

ended up with a Taisol 744092 (their good one) from KD. Their UPS ground is overnight to me here in MN . arctic silver II also, $23+$8+7 shipped, not that bad. Now i've only got to get rid of the Orb, hehehe.

 

[Compellor]

<< Anyhow, can someone tell me if 3.7v I/O is too high? >>


Yes, it is. Run it at the default voltage of 3.3v. If you notice lockups or crashes, raise it until the machine is stable. That much voltage could fry you memory over time, and isn't needed unless the machine isn't stable.

 

[jimmypop]

KT7A's default voltage is 3.4 VIO: I've toned it down to 3.5. Sound ok? Otherwise i get a bunch of nasty system errors/random resets. If I remember right Kingmax PC150 is only actually rated at 150 cl3. I'm running it at CL2. Don't want to lose the extra boost though .

BTW, got my Taisol 742092 today, arctic silver II. Posted at 1100 . I think I'll be able to do a stable gig with no problemo. This thing is a monster too...and actually seems quieter than my Chrome Orb! Go figure.

 

[jimmypop]

Well, final results are in. I don't know what's up, but I can only get stable at 6.5 x 152= 988. Oh well, my quest for the gHz club is thwarted. I'm running a good 15c cooler that I was with the C-orb, and at 1.8/3.5, which is probably a lot safer too.

 

[gtd2000]

Jimmypop check out my Duron OC thread and tell me if you get the same problem?
