Dell cites overclocking issue with high-end quad-core PCs

post #1 of 40
Thread Starter 
July 16, 2007 (IDG News Service) -- Dell Inc. has stopped taking orders for one model of its high-end desktop PCs, citing issues related to overclocking quad-core processors from Intel Corp.

Dell's XPS 720 H2C is a S$5,939 computer designed to boost video game performance by combining two Nvidia Corp. graphics cards with Intel's Core 2 Extreme chip, "overclocked" by Dell to run at a higher frequency than Intel intends. The computer uses a liquid radiator to dissipate the extreme heat generated by the setup, a more expensive design than standard air-cooled PCs.

Last Wednesday, Dell told customers that it would no longer accept orders for the "bin +3" version of the computer, which runs Intel's QX6800 Extreme Edition processor at 3.73 GHz instead of the 2.93 GHz it was designed for.

"We apologize for having to do this, [but the] truth is that we do not have a line of sight to enough supply of QX6800 processors that can tolerate the Bin+3 overclocking," Dell's digital media manager, Lionel Menchaca, said on a company blog.

"At this point, our engineering team is doing everything they can to get more Bin+3s out of our original supply, but this is expected to be a slow process," he said.

Dell asked its customers to cancel their orders and choose an XPS 720 PC with a slightly slower QX6800 chip or with a slightly less powerful QX6700 chip running at the same speed.

Intel stressed that there is no shortage of the chips themselves.

"They're taking these units that run at 2.93 GHz and overclocking them, although we guarantee them at 2.93 [GHz] only," said Intel spokesman George Alfs. "We're certainly proud of the headroom of the Core architecture, and we're aware of them doing this, but once they start overclocking, it's their responsibility to support and warrantee the chips."

Dell said it expected to have enough 2.93GHz chips that would tolerate overclocking.

"It just comes down to physics -- a design can only tolerate so much voltage," Menchaca said on the blog. "When we started taking orders for the 720 H2C, we had a fixed supply of the QX6800 chips that seemed ample at the time, but once when we found out how rare the Bin+3 variety was, we started combing our supply chain for even more.

"Last week, our backlog forecast started to pass our best estimates for finding Bin+3 chips. It just did not make sense to take any additional orders when we couldn't tell when we would be able to fulfill them."

This is the second time in recent months that Dell has delayed shipments of PCs in its gaming and enthusiast family. In August 2006, the company stopped shipping the similar XPS 700 model while it fixed a design mistake in the cooling assembly.

I figured this would happen. Those quads don't like to be overclocked that high very often.

i bet they're still loud. those computers ship with 1000 Watt PSUs.

and are that many people really lining up to spend $6000 on a computer? my god, i gotta get in on this market.

Unfortunately, this may continue to happen with Dell. They are doing everything they can to compete in the gaming/enthusiast market that they are really pushing the limits. This probably just generated a few angry customers who most likely won't go back to dell again for something like this just because of other companies who sell those ridiculously expensive "super" towers as i call them.

Until now I didn't even know they offered an overclocked high end PC, like dorian said, if you overclock a dell, you KILL IT. Watercooling isn't going to help that much when it comes to a dell, because "dude its still a dell"

Looks like Dell killed themselves on this one. Good job guys

I was reading reviews of this system and they were having crashes all over the place. You couldn't get these things to run multiple primes for example... shame on Dell...
