Nope. If you go too high you'll know it and it will reboot at default settings so you shouldn't ever have to manually clear CMOS. fyi, don't set memory timings tighter than 2-3-2-6 no matter what you have or even at higher CAS the other timings can't go lower than I've indicated. Other than that you should be fine. If it ever won't reboot after giving it a moment just power switch off then on, turn the pc on and pull the power cord as it starts to boot up. That'll reset the CMOS automatically every time.

Yes it is a DTR CPU and it is a C0 Revision. Any motherboard that supports DTR processors should support your CPU maybe even many that support the 1.4v mobiles. Just check through the motherboard list on the first post and see which ones have been tested with a DTR CPU (look in the [ ] area)

Did you mean the motherboard that supports DRT processors and it can modify the voltage to 1.4V.
and then my cpu can work properly.
i know my cpu is 1.5V and i know many motherboards
just can modify the voltage to the limitation, 1.5V.
If you konw that. can you recommend me some motherboards?
Thank you.
sorry, I bother you with my little affairs.
 
Your DTR CPU runs at 1.5v but that doesn't mean that you can use any motherboard that supports that voltage. Only very few motherboards will work with a DTR CPU. If you look at the first post in this thread there is a section that lists different motherboards that work with mobiles. Each motherboard also lists what CPUs were tested with the motherboard. Look for which motherboards have been tested with DTR 1.5v CPUs. It is also my experience that most if not all motherboards that support 1.4v mobiles also support 1.5v DTR CPUs but I cannot guarantee that.

Personally, I really like the ASRock K8S8X. However the voltage for your CPU will only go to 1.55v so your overclock will be limited by that but you should get a nice overclock even though. While I had problems with the board and don't recommend it at all, a lot of people seem to like the Asus K8V Deluxe. But that board doesn't have AGP/PCI lock so you can only get about 220 HTT so your overclock will be very limited. Another choice is the Chaintech VNF3-250 but that board requires that you have a desktop CPU to update the BIOS before you can use the DTR CPU. And that board seems to have quality control issues. Another option is the Gigabyte GA-K8N Pro but it uses the old nforce3-150 chipset and all the devices are on the PCI bus so you could have performance degradation because of that.

I have (though it's not a DTR, it's a low power mobile), it works reasonably well in my AK89 MAX. Right now I'm running at 250x9 (2.25Ghz) with 1.3 volts, but cannot go higher as i am at the max I can set. I will be ordering a VNF3-250 and, if I'm lucky, will really beable to see what this chip can do.

On the AK89 with the Low poer CPU just use clockgen to keep increasing the FSB.

On another note, the EQ3801 works flawlessly with DTR CPU's. I have mine running with a 1.4v 64 2800+. I'm running at 275FSB 2.2GHz and 1.5v

Here is my info so far. http://www.hardforum.com/showthread.php?t=772449

I have been unable to get clockgen to work properly with this cpu/motherboard combo. If I increase the clock past 255MHz it useually hard locks regardless of other settings.
 
Ok got my VNF3-250 up and running, working great so far. I'm currently at 281x9 (2.53Ghz) with 1.5 volts on my 2800+ 35watt mobile. Checking to see if its stable, will post back later.
 
zzf is showing the k8n-e in stock, i think i will give asus a call either tomorrow or Monday and see if they say they are supporting dtr's/mobiles if i get a confirmation i will order the board. Anoying as I just sent back the msi yesterday (and just switchted it for the asrock over last weekend), I had till next week to send the msi back, had i known the asus was coming out this fast i would just have gone strait to it, as keeping the asrock for a week seems silly, but hopefully it works and it is realy out.


just sent an email to asus, will post when i get a response or if i get a response over the phone.
 
probably will order on monday or tuesday, would prefer to get some kind of confirmation that it will work as 1 more swap of boards should be it for the summer, and if it doesnt work i dont want to have to deal with putting the asrock back in. Also i have already rm'ad a stick of ram, and the msi, both from the same place i am ordering the asus (though the asrock was from a nother) so i dont want to rma anything else to them this summer.😎
 
You sound like me when I ordered the MSI. I just didn't want to do another swap (it gets very old very quick) and stuck with the Asrock. As soon as I found out about the crap MSI is still putting out there I was glad I hadn't wasted my time. Well, if you do go through with it please let us know asap as my curiousity is piqued.
 
For cool and quiet computing, I'm extremely happy running the A64 3200+ 1.5v DTR on the MSI K8T Neo FIS2R.

The system first initialized at 1.1v and ? MHz. Setting the Vcore to 1.5 v allowed it to initialize at the stock 2GHz. BIOS is Ver.1.6 (the shipping BIOS). There are no multiplier settings in the BIOS; HTT is adjustable from 190-280MHz; Vcore is adjustable from 1.4v to 1.55v.

At stock speed and 1.4v Vcore, the idle temp is about 11C above room ambient and running Prime 95, it's about 21C above room ambient per MBM. And the system is virtually silent. Cool 'n' Quiet does not seem to be supported, but the system runs great without it. The CG stepping, plus the large die size of the 1MB L2, plus the absence of an integrated heat spreader seem to work extremely well. (I used washers on the HSF attachment screws to make up for the lost 2mm of IHS thickness.)

One of the best features of the K8T Neo is the beautiful red PCB. It looks great in my window case w/ a red cold cathode light!

Errata:

The system would not POST at first. The "D-Bracket" stopped on the second initialization step. It was necessary to clear the CMOS; then all was well. (But, jeez, what a problem to diagnose.)

I could not complete a "Repair" installation of Win XP, so I had to do a clean install... Here's the fatal error message: "The procedure entry point Get UMS could not be located in the dynamic link library MSDART.DLL."

But it was well worth it!

Thanks to you all for your postings on this topic!!
 
Thanks for this thread Bar81; been reading / lurking for a while now...

On the Asus board; gameVE.com says they'll get them 7/14 so if ZZF goes out look to them next as a friendly heads up..

and I'm eagarly waiting this response; I've been drooling over 754 for a while now and with Clawhammer desktops fading fast the DTR looks nice.

Just a quickie though; newegg.com has 3200+ DTR refurbs for $225 (nice deal 🙂 ) now I'm thinking 80-90% of those are from people who didn't know about incompatability or got stuck with 800mhz.. think its a safe bet that I'm right? To that end maybe someone here can tell me if it's possible to RMA a refurb if I don't like the OC a-la regular item? (note: I wouldn't RMA a product I broke, thats evil)\

thanks guys

Thanks, I'll add it to the list.

Yeah, I would think the refurbs are exclusively either from people who didn't do their research or didn't get a crazy overclocking chip. Either way that's a great deal for a DTR and you should hop on it if you're looking for one. My understanding is you have 7 days to rma a refurbished CPU from newegg for whatever reason.
 
excellent thanks Bar81; I've been trying to jump ship on the AMD 3200+, K8V $179 deal but if it's down all week I'll probably go for the DTR K8N-E combo; if I'm gonna pay that kind of $$ I'm gonna do this right 🙂

of course if the K8N-E lacks DTR/Mobile support... well, in Asus I trust...

I'm wondering the same thing. It doesn't look like it, but ...?
Click to expand...

I would try the GIGABYTE "GA-K8S760M" since it uses the same/simlilar chipset (sis) which has proven to work with both mobiles and DTR's.
 
just got off the phone with asus they say it wont be supporting dtr's but i am not entirely sure that they even new what a dtr was, so i dont know. I want to buy the board, and I want it to work, and since their other boards do, i would guess it will. Anyone want to try it out first as I would prefer not to be first this time (the k8n-neo platinum was enough for that for this summer).
 
I'm definatly going to get the Asus board, but seeing as that will be my virgin foray into A64 territory I might not go for DTR/mobile unless someone can answer this question for me;

if the DTR / mobile does not work can I return it to newegg for $$$ to get a reg. A64 with or can I onyl return for the same CPU, also is there any cost invovled?
 
you can definitely return it to newegg, you may be charged a %15 restocking fee, though if you are getting another chip from them they might be willing to wave it.
