On BF the 840 will be the same price.

the 840 doesnt have the cache iirc. still a good buy.

MEASURE! I know the CCF120 is as big as I can get. I glued a 1/4" thick fabric pad to the inside of the door to my case when I bought it, I had to cut it off from above the CCF when I bought the cooler, it's still much cooler and quieter thanks to the big, slow fan.

True that. Here's the thing if I have this chip OC'd to 3.5 and an hour into Prime95 it's reading 55 degrees celcius steady across all cores do I really NEED a better cooler?

Yes! Get the 840.

High settings, 8X AA/AF 1080p, 512mb 4870, and I don't notice any slowdowns after everything's loaded in (probably 30FPS or better)

This cpu has a locked multiplier right? Can you share your overlock settings?

Thanks

I bought the 840 a month ago and boot it up to my PII 545's setting...3.8ghz. I started tweeking and finally got 4.2ghz (1.575v, 15.0x280, NB is 2240mhz, HT is 1940ish)

multiplier is locked;its cheap...can't complain.

It ran prime95 just fine, been encoding for hours while playing a game... This is the latest setting, before it was solid 4.125ghz@1.525v.

I have not seen others get great results for OCing this model (~3.7-3.8ghz)...prob not alot of hard core guys who buy this chip.

I run a Spire Thermal Eclipse II....temps in 50s loaded for summer....winter is not even 40s..actually barely touching 30c 50% load.

I figured the extra 100-200 mhz would offset the missing L3 cache, after OC. Quads for $60 bucs???...bang for buck!

I have been wanting a hex core, but monitoring cpu usage, I barely max this out...even encoding two movies and surfing....I dont think it will help me any....now waiting for good video card.

I wasn't aware, so I did some research. The 840 has no L3 cache at all, it's basically just an 3.2ghz Athlon II X4. The 830 of course is 2.8ghz and 6MB of L3 cache. 400mhz difference for 6MB of cache.

These are the closest CPUs in the AT bench...

It looks like the extra clock speed (the 840 would be 100mhz higher even) wins out over the L3 cache more often than not, but for a few certain tasks the 830 would be better.
