Overclocking The Intel Pentium D Processor 805

The Intel Pentium D Processor 805 was silently launched by Intel and many enthusiasts may not have heard about it yet. Legit Reviews recently purchased the retail boxed processor and went right to overclocking it to see how the 805 performs. At 2.66GHz with a 533MHz FSB the processor doesn't sound fast, but come see how it runs at 3.8GHz!

We ordered our Intel Pentium D Processor 805 from ChiefValue.com for $130.99 last week and currently they are priced even lower at $129.79 shipped. For the overclocker getting a 3.8GHz processor that needs no voltage adjustments for $129.79 shipped is nearly unheard of. To make things even better a high-end enthusiast motherboard is not needed for overclocking as running under 200MHz FSB is no big deal.

This is a sweet little CPU! I can't wait to get mine up and running!

it's sure a nice cpu. it's hard to think that a cpu that from the specs point to be an okay cpu yet it performs quite well. Not to mention that it clocks crazy.

On paper the Intel Pentium D Processor 805's 533MHz FSB and the 2.66GHz clock frequency make it sound slow to enthusiasts, but like you noted when overclocking the processor really wakes up. I almost wonder if Intel did something with the PLL's in the processor to limit the FSB operation. I've seen several reviews on the processor now and none were able to get ther processor much over 200MHz FSB and two were done on unlocked ES CPU's with a multi of 14.

130bucks!!!!

Sweet OC mate!!!!!!

maybe intel is afraid that everybody will buy this instead of the more expensive models

I was looking to upgrade from my A643200+ which is a socket 754 to posiblt one of these. Even with the OC the SP scores seem around what I get now. Would this be worthwhile in my case? I suppose it would help as I do alot of multi tasking, and could always upgrade later. Or would it serve me better to go with a Socket 939 AMD where I could use my current ram and then buy up when people sell off for the new Socket AM! (is that right?) Anyhow, I just want to go dual core, and on the cheap and get away from agp. Is this a good choice?

That is a tough call... keep in mind that Intel's Conroe and AMD's Socket AM2 are both right around the turn. If you can wait 3-4 months then you will have much better processor cores to pick from and further price cuts. Right now I would stay AMD, as you wont have to upgrade your board, memory, and so on before the new stuff comes out.

If you want dual core on the cheap then this is the way to go... and I'm selling the CPU i used in the review in the sale thread for $125.

I may take you up on that. My question is will it be basicly the same speed only better multitasking, or overall will it be slwer using sing aps than my current 3200+. I was only thinking of going 939 so I could reap the benefits of people selling off their old gear. I just dont have funds to put into PC's like I used to. Being an adult stinks, bills and all that good stuff. So if I got a 939 I could go dual core and basicly just need cpu/MB, if I go intel I need to add ddr2 to that as well which is really just another $160 or so right?

All the next generation platforms are going DDR2 and it's really not that expensive. CORSAIR VALUE SELECT 1GB (2 x 512MB) DDR2 667 is only $77 and if you wanted performance memory you are looking at OCZ Gold Series 1GB (2 x 512MB) for roughly $107 for CL4 memory timings. I would think the Intel would be better at multi-tasking... You have dual-core and dual-channel memory that would all help multi-tasking versus your current s754 platform.

I agree on the adult part... I'd do anything to go back to high school or even college...

Hello,

I'm really excited about overclocking the D 805, but what type of cooling system is needed for the processor? Is it hard to install? Also, how many watts should your power supply be? Can it run on a 350w?

Many thanks,

Miro

i'm fairly new to overclocking, and i'd really like to try this 805 processor out. i've got a pretty good grasp of how overclocking works except for one aspect... the memory. i'm really not sure what kind of memory i will need for this. my goal is to overclock it to about 3.6 or 3.8 with stock cooling. if i absolutely need to upgrade my cooling, i will... but anyway... i'm looking at getting the Gigabyte GA-8N-SLI motherboard (http://www.newegg.com/product/product.a ... 6813128316). it says it has a FSB of 1066/800Mhz, so does that mean i need to get DDR2 800 memory? I've been researching this processor a couple different places to see what kind of memory overclockers are using with it... and i've seen some people using DDR2 533, some using DDR2 667, and others using DDR2 800... how do i determine which one of these speeds to use?

Apoptosis,

I was over at Tom's HW and they got this bad boy CPU to do 4.10Ghz written up in a 45 page report. A 54% increase! Intel has a nice sleeper of a chip with that much horsepower under the IHS.

If you got this chip, give it try with water cooling. It will only put out 274W of heat!!!!

Still, not shabby of Intel and a dual core to boot! It almost makes me wantto use an Intel system for a change.

this article was written using the Corsair Nautilus 500 as the cooling solution ;) So all the testing was done under water. That's all she's got captain!

For starters the CPU i bought to write this article is for sale, so if you want it let me know. When it comes to the memory I couldn't get over 740MHz when overclocking because the dividers were not there. If you are overclocking some decent 667 or 800 memory should work fine. I'd be tempted to get 800MHz because that is where the industry is moving to as the next standard setting.

Almost, there's a mod that can be done to the Nautilus 500 to boost the cooling to 560~600W. However, it requires more than a wrench or a screw driver to tweak it.

Hello i bought a pentium d a while ago and only jsut needed help with it. I was giving a 6600gt the other day and mistakable bought a Asus P5GPL-X.
i was jsut recently informed after buying it that they do not work togther i was wondering if i could flash the motherboard so i could use my pentium D 805 with it with no hassal.

if you have any ideas on how i can get it working i will be very greatful. Just send me an email ([email protected]) if you get an idea.

Kind Regards
Michael

P.S
i already asked if i could return it and they said no.

The 915 chipset that the ASUS P5GLP-X uses does not support ANY dual-core processor, so there is no hope for a flash or anything like that. If you bought it from an online retailer you might just have to pay for the restocking fee, but I can't believe a store wont return an unused motherboard for you when you bought the wrong one.

yes it did quiet piss me off too.
well thats the last time i buy anything from nintek.
thanks anyway

Would anyone ehre also know why it will overclock to 3 Gigahertz but it wont boot windows? and also when i put it up to say 2.8 it will run fine then i get into bf2 but after about half an hour the game will jsut exit?
