Prescott CPU wrecks another motherboard

[bigbeark]

I must be one of the few still using my old Netburst machines, but those Presc-hotts just fried another of my Intel boards. Are the Cedar Mill CPUs any kinder (cooler)? What would you recommend?

Re: Prescott CPU wrecks another motherboard

can your mobo run an E6600? those are cheap.

Re: Prescott CPU wrecks another motherboard

^ That's what I'd recommend. If it can't run Core 2 Duos I'd suggest finding a newer motherboard and a Core 2 Duo. Both can be had for less than $40 USD, looks like a bit more up in Canada.

Here's about the cheapest I can find, http://www.ebay.ca/itm/331572430440
Intel DG35EC with a Core 2 Duo E8400. It'll be a huge upgrade and you can probably reuse everything off the Pentium 4 sans ram if that's DDR rather than DDR2.

Re: Prescott CPU wrecks another motherboard

Most HT/netbust processors are socket 478....not very likely you'll get an LGA775 C2D to work in that.... If the motherboard is toast, I most certainly wouldn't replace it....time for something a touch more modern.

Thanks for the link! Might just do that.

Re: Prescott CPU wrecks another motherboard

I went back to Northwood CPUs in my P4 machines. I find the Pentium HT 2.6GHz to have good performance and low power consumption.

Re: Prescott CPU wrecks another motherboard

Yah. I find that you can get used C2D PCs so cheap now that you can't even give a P4 machine away.

If we end up being left with a P4 PC at work, it just goes straight to the metal recyclers, even if it is working fine (although I may scavenge and recap or re-use the PSU if it's decent enough)

Re: Prescott CPU wrecks another motherboard

Yes the Prescott's run hot and knowing that you can't really blame the cpu for killing the motherboard if you don't use proper cooling. To make any good recommendation you need to tell use what board you are using (aka socket and chipset at least).

Nothing wrong with the Netburst Prescott CPUs. Intel just designs crappy CPU VRMs on their motherboards. If I had a penny for every Intel motherboard with discolored/overheated CPU VRM, I'd have some serious pocket change by now. Put one in a MSI motherboard, and I guarantee you'd never have a problem. Heck, even ECS does a better job at VRM design. I bet your board has a shorted FET on the CPU VRM.

The old Foxconn motherboards that Dell used are pretty solid too, sans the caps. My OptiPlex 170L is still kicking. In fact, I am about to retire my Pentium 3 PC (HP Pavilion 8756C) right now to put the 170L in its spot, which has a 2.8 GHz Prescott.

Anyways, if you have socket 775, check your motherboard's manual to see what CPUs it supports. You may be able to put a C2D in it. If not, then go with a C2D and new motherboard. Used C2D chips are super cheap on eBay now (at least the low and mid-end, not the high end ones). If the P4 CPU did everything fine for your before, the C2D should be more than enough for a while. Not to mention it will run cool and consume much less power.

If you are going to spend $40 to $50, I suggest checking your local kijiji for systems with a dual core processor.

I looked up your area and set $50 as the maximum and found the following. Remember to negotiate on kijiji. If they ask $50, offer $35 or $40.

If the description is correct (ask seller), then this deal is the best bang for the buck. Pentium quad core 2gb ram for $30.

There are many others under the $50 mark that are dual core, 1 to 2GB DRAM and some with hard drives and Windows 7 COA. I won't list them all, but you can easily search on your own.

PS. All my systems at home that are dual core or quad core were found on local ads from people who gave them away for free as non working. Usually the culprit was a single bad capacitor in the power supply.

There's no way that's even a dual core. Anything dual-core or quad-core Thinkcentre releated would be Lenovo branded. I'm guessing the seller's taking Pentium 4 as Pentium, 4 cores.

Edit:
Looking on there there's a few things.

Some Acer with a 1.8 Pentium Dual-Core for $40. http://www.kijiji.ca/v-desktop-compu...ter/1075273253

HP DC7800 slim tower for $50, 2.33 Core 2 Duo. http://www.kijiji.ca/v-desktop-compu...key/1085026233

Custom tower with an E8400 for $65, http://www.kijiji.ca/v-desktop-compu...ghz/1062520573

Lenovo M57p for $70. No processor speed listed but it'd be a C2D. http://www.kijiji.ca/v-desktop-compu...57p/1075519005

Re: Prescott CPU wrecks another motherboard

The one thing I hate about those slim desktops is how everything is non-standard form factor.

Re: Prescott CPU wrecks another motherboard

that's intentional, they probably learned it from Dell.

Re: Prescott CPU wrecks another motherboard

Where I used to work I had two core2's available for sell for upgrades, an E6600 and E6550. If one was sold, I would get the money for it. My boss (a 48 year old ex manager of a plastics factor who did computer work for hobbying) put the 6550 in a customers Pentium D motherboard, after I told him not to, he said 'fuck off'. I knew the motherboard was not core compatible and ran much higher voltage, too much for the chip. He turned it on, with a black screen, and a burnt silicon smell coming from it. He burned the chip. I said, I told you, congratulations, you owe me for the processor. He said simply 'fuck off'. I told the owner, he said he would talk to him. I never got my money

[rhomanski]

Re: Prescott CPU wrecks another motherboard

Sorry, but it's obvious he was more valuable to the owner than you. I've been in that situation, it makes you mad. Not much you can do about it though.

Wouldn't surprise me if he bent and shorted socket pins.....

Possibly also forgot to clip down all the heatsink push-pins.....

Sounds like a moron.

no, he put the PD back in and it booted up fine. I saw him take the c2d out and I didn't see any bent pins. Pentium D is 1.2v minimum, Core 2 E6x is usually 0.8 - 1.5v, but the startup voltage of this motherboard might have been different

We were building two identical computers for a customers business (I built one, he built one) when I was switched to contract (without notice or being notified so I could not claim unemployment). I finished and brought it to the shop when the customer was called to pick them up. I put mine in the original computer case, he did the same to his, the customer picked up HIS case and we heard a fairly loud bang inside. He forgot to screw the hard drive in. He had to take it back out and screw it in. So embarrassing for him.

65 nm Core 2 is 1.2 V for the norm. (1.5 V is the max allowed for overclocking)

Re: Prescott CPU wrecks another motherboard

I think a lot of Intel branded boards actually, if you check the integration guide, says not to install Prescotts in them. At least my DQ45CB does not list the S775 Prescott as a valid CPU, most likely due to the VRM not being correct for them.
I unfortunately had to go get one of these boards because my Gigabyte EP43-UD3L stopped working properly, but the Gigabyte board does list the Prescotts as valid CPUs. I currently have a 3.4GHz Prescott in that Gigabyte board while it's being tested.

The DQ45CB got the nice Core2Quad Q9550S to run, which probably is very easy on the VRMs. It was the cheapest on eBay at the time that supported all the old hardware the Gigabyte board had.

I still have yet another 3.4GHz Prescott in a S775 MSI Neo3-F which doesn't support Core2 CPUs officially. Unless I get a really cheap Core2 to test, I don't think I want to try to see if it will work with them for fun. Would be nice to have a Core2 board that supports DDR1.

I think they got some of those!
