Athlon XP 1600+ @ 166/333 mhz?

[vicwang]

With rumors swirling of a TRUE 166/333 mhz bus in the upcoming nForce 2 boards, can I realistically expect my XP 1600+ (bought about 6 months ago) to successfully overclock to 25% past spec? My system is pretty well cooled with a Thermalright AX-7 with high-speed 80mm Panaflo, high-speed 120mm intake, and 80 mm exhaust, and I can overclock to 147/294 successfully in my ECS K7S5A board (anything past that and the board can't handle it). Just wondering if I'll actually be able to take advantage of the 333 mhz bus without upgrading to a 333 mhz Athlon XP's (which may or may not be coming out).

Do you know the stepping? How much voltage can you supply? You may need to give at least 1.85v actual. I've got a recent XP1600+ (AROIA) that can do 1700MHz with my cheapo cooler. Of course, my Abit board is undervolting -- the cpu is getting about 1.82v. Anyway, it sounds like you have good cooling. Getting adequate voltage will be important, and a bit of luck too of course.

If you bought it 6 months ago, I would say don't expect it. You might get it but I would say your chances are slim.

Now if you get a new 1600+ from Newegg (or a few other vendors) you'll get a good stepping -- an AROIA or AGOIA... get one of those and you'll hit it easily.

My 1600+ does 1766 (I think that's 2100+) right out of the box -- at default voltage. That's Prime95 stable mind you. Most people get about the same results.

Looking at the cpu database at overclockers.com you should have a chance of 1700mhz, but above that is a lottery. I have a 1600xp coming tommorrow I will post results with it in my koolance case.

 

[vicwang]

Don't know about the stepping but I can find out. Right now I'm running at default voltage, since my ECS K7S5A board doesn't allow voltage adjustments.

I think grunjee is right that a 6-month old XP1600+ might be pushing it. But if you can't hit 10.5x166, you can always unlock the chip and knock the multiplier down. Or spend the 60 bucks for a new XP1600+...

With all discussions about how great 1600+ with stepping AGOIA can be overclocked, I am wondering what is the bottleneck in my machine because I am only be able to get it to 10.5 x 152 stable. I have Abit KX7-333 board with 512 mb Crucial 2100 and an old Nvidia Quadro graphic card. I can go into Windows with higher FSB but when my CPU temperature hits 56°C, my machine resets itself. Anyone has any suggestions?

 

[grunjee]

Oh man, you need a mobo with Vcore adjustments. I'd recommend the 8kha+ or 8k3a/+.

What's your Vcore at?

 

[ktch]

I can put it up to 1.85v but right now I keep everything at default in order to hold my CPU temperature about 56°C.

Grunjee what sort of cooling equipment are you on to get your cpu running at such a high oc? Also what power supply are you on my friend, im very interested. Also do you think that an XP1800 would overclock as well or is there something special about XP1600's atm?

Thanks, Mark

I watercool... my setup is an Eheim 1048 pump, a D-Tek rad (heater core) and a Danger Den Maze2 block.

I recently (2 months ago or so) upgraded my psu to a PC Power and Cooling 400 Watt Silencer. I love it and all, but it probably wasn't necessary... my old CompUSA performed just about as well (as far as the 5V rail goes).

One more thing... to get an OC like mine doesn't necessarily require watercooling... if you have a good enough HSF you can do it on air as well.

Edit: Sorry, I forgot to answer your other question. I'm not sure about the 1800+'s. What makes the new 1600+ chips so special are the new steppings -- AROIA and AGOIA. I think there are AROIA and AGOIA steppings for the 1800+'s but I'm not sure. I would still get a 1600+... no sense in spending the extra $$$ on an 1800+ when you'll probably get the same (if not a better) OC with a 1600+. You've got a 99% chance of getting a 2000+ rating right out of the box... and very likely to hit 1.8 GHz or more. For $70 shipped or less, who can argue with that?

 

[xroyal]

I know of an early brown 1600+ that will hit 2000+, so your voltage may be the chief culprit.

I have new 1600+ @ 1800+, and I love it! After unlocking should go to 1800 MHZ and above.

Sounds like you need better cooling my friend. I've got a cheapo cooler (I think only rated to 1700+) running my XP1600+ at about 1700MHz (just over 2000+), my voltage is 1.82v indicated, and my temps (also on an Abit board) are much better. How's your case and system temps? What cpu hsf?

I have an XP 1600+ AGOIA on a MSI 745 Ultra. The board also undervolts a bit so I did a voltage mod to get 1.95v. I just bumped it up to a 190MHz FSB (9.5x190MHz=1805Mhz) - was running 1830MHz (10x183MHz) before. BTW, this is with a 256MB stick of Crucial PC2100 and an AX-7. Runs rock stable.

Holy crap, 190 on a stick of PC2100? That's insane. My Crucial 2100 will do about 170 (max aggressive timings up to about 163) but craps out after that.

Holy crap, 190 on a stick of PC2100?

That's what I said each time when:

It booted.
It loaded Win98.
It ran Prime95 for several hours
Ran 3DMark2001SE benchmark several times
Bad news - at 9.5x190MHz the 3DMark2001SE demo loop at 1024x768 crashed after several loops. Then again, MBM showed the 5v rail under load dropping to 4.68v (this is with a 300W PS). I believe the AGP draw under continuous load is pushing the 5v rail into No Man's Land.
Good news - to test, I've backed down to 8x190MHz. It looped the demo longer with no problem, but I stopped it to check the forums. The lowest the 5v rail dipped was 4.75v. Guess I may need a beefier PS to play a bit more

BTW, it'll boot into DOS at 195MHz, but Win98 gives a Windows Protection Error. I haven't played any further with memory timings, though.

Curiously enough, MSI updated the 745 Ultra BIOS for "better DDR333 compatibility." They also killed whatever Crucial PC2100 magic was there. Back to the old BIOS.

The more I use this board, the more I wish SiS could have been AMD's initial partner than VIA. USB is still working fine at 190MHz and as a bonus my trusty old Diamond MX300/Aureal Vortex 2 card works perfectly without the registry/latency patches my old VIA board needed.

Thanks for you response man I appreciate it I was thinking, what could I acheive with an XP1600 with some serious aircooling, like a SLK-800 with a 84cmf delta fan on it and a few high cmf case fans. The SLK-800 is the best socket a headsink on the market bar none but its is expensive however. This is some serious aircooling.

I'm still looking at a 1.6a oced system though too tbh I really don't knwo which to go for, with the XP1600 I can afford much more cooling but the 1.6a is so overclockable....

Argh.

Thanks, Mark

Hi Jaybee,

I opened my case and run CPU at 1.85v, vio at 3.65v and vddr at 2.85v. I am able to push FSB to 162 and gets into windows but when I run cpu benmark from Sisoft Sandra, my machine gives me memory problem. My system temperature is 35°C and my CPU temperature is 54.5°C. Do you think Artic Silver can help me to reduce the CPU temperature down further under 50°C?

 

[rancherlee]

Asus Nforce board with a 0208 AROIA chip
10.5x167 = 1754mhz
reached it at defualt (1.81V on my board) with a weak power supply (300w antec)
Runs Prime 95 Stable @ 1.86v and my 5V drops to 4.72v (around 4.92 @ idle)
Tried 10.5x172 (1806mhz) with 1.86v and the 5V dropped too low and prime would crash after a few minutes
with a New powersupply I SHOULD be able to take this chip alot higher.

Ok, you're at 10.5x152? What happens at 1.825v? Also, can you run at a lower vdimm? I'm curious how you got to those settings -- are you sure the box is unstable with a lower vcore or vdimm?

You need to drop your system temps. What's your case cooling like? Also, what are you using for cpu/hsf interface now? Thermal pad or some other grease? If it's grease, AS will be good for maybe 1-2C.

jaybee

PS It sounds like you can run at 10x159... but on second thought I bet your cpu is still locked, isn't it?

 

[ktch]

I am now be able to run it at 10.5 x 158 with my case open. My system is at 35°C and my cpu is at 54.5°C with vcore at 1.775v, vio at 3.65v and vddr at 2.75v. I used generic thermal paste for my cpu and hs/f and my cpu is still locked.

Sounds like you are at the end of the road -- for now. Your memory won't take 162fsb and your multiplier is locked, so you're about as fast as you're going to get without new ram or unlocking.

jaybee

PS What happens with the case closed? How do the load temps look?

 

[ktch]

With my case close, the system is about 41°C and the cpu is about 60°C. Do you think it is worth to unlock my cpu?

Guys and Gals,

I just got a AXP 1600+ AROIA stepping from newegg...I also brought some PC2700 OCZ rebranded ram for overclocking it. I'm not getting the result that I was expecting. The system is currently running stable at 155x10.5 without any problems, thus so far. And at that setting my CPU temp is at 56 and MB temp is around 36 or so. I do notice that when I do pump it up higher than normal..it takes the board (Shuttle AK35GT2) longer to boot up the system. If I do set it higher than 155 FSB it crashes in loading up windowsXP or sometimes not boot up at all. Any help is appreciated.

Here are major the component on my system:
420W Antec True Power Supply
GC86 HSF (sp?)
TNT2 Pro PCI
AGP Geforce2 GTS
generic network card
