Haven't noticed much change with 0.121, most of the big changes were in 0.121u# releases
gauntleg is about the same, runs fine speed wise but still likes to lock up at random.
blitz is down a little maybe 5%, I suck at this game totally so haven't tried in game lately.

Good to see you've got your PC up and running well, and welcome to the fast lane. what heatsink are you using by the way?

--- Quote from: metahacker on November 27, 2007, 08:53:18 pm ---can you try a comparison to your regular benchmarks with the following in your Makefile ARCH= line ?

-march=nocona -mtune=nocona -minline-all-stringops -maccumulate-outgoing-args -mmmx -msse -msse2 -msse3 -mfpmath=sse -funroll-loops -fomit-frame-pointer

and perhaps even compare that to

-march=pentium-m -mtune=pentium-m -minline-all-stringops -maccumulate-outgoing-args -mmmx -msse -msse2 -msse3 -mfpmath=sse -funroll-loops -fomit-frame-pointer

I've been really busy of late, but if I get a chance in the next few days I give it a go, mind you it will have to be a 32bit build, 64bit builds are still beyond me.

Taz do you think it would be worth the jump to a 6850

Tiger-Heli:
Taz - that helped a lot.  What I am mainly looking for is the ability to play some of the more demanding games like Cruisin' and SFrush.  Based on your specs (150-200% in these games), I am hoping a E2100 at 3 Ghz or so might give 75% performance, which would still be around 100% (and I could live with less than 100%, but 60% is not playable).  I don't plan to go to 64-bit, and understand that it's not a totally linear scale.

I just have a couple of additional questions, but your replies already helped a lot!

As far as coolers, any idea how the Arctic Cooling Freezer 7 Pro would compare with the others?

Still true with XP?  (I've read reviews that said dual-channel wasn't that important and was thinking of getting a single 1GB stick to keep some ram slots free - not sure the reviews were of dual-core systems, though).


--- Quote ---Any half respectable DDR-800 ram will do just make sure it's compatible with the P35 chipset, there are a few Dimms out there that work great on the older Intel chipsets and with AM2 CPUs but are totally unstable withe P35 chipset.

How can you tell? (Or do you just read tons of reviews?)

TigerHeli:

I have run my computer with and without dual channel configuration and it makes no difference whatsoever even if the bandwidth is improved in synthetic benchmarks.  I tested it with mace and with the "Splinter Cell: Pandora Tomorrow" computer game which I have installed merely for benchmarks as I don't play PC games (or mace for that matter but it makes for nice benchmarks).

My PC is an e4300 which I am running at 300FSB for 2.7GHz although I ran it at 3.0GHz for a week or so before it became unstable.  All of this was with stock voltage and cooler.  The motherboard is Abit IB9 which is the Intel P965 chipset.  Memory is 2GB DDR2-667 running stock although I can run it at DDR2-800 but I don't like to push the memory long term as I don't get any benefit.  Video card: old Geforce PX-6200TD unlocked to 4 pixel pipelines.

If you are interested, I can run a couple of configurations that you might want to consider as long as they don't exceed 3.0GHz for the CPU or 800MHz for the memory since I don't like to mess around with voltages,  to help you make up your mind about what you need to purchase.

If you don't plan to increase voltages, I don't think you need any fancy coolers.  My CPU runs normally with a 67C reserve to the maximum Tjunction temperature according to CoreTemp.  Under Orthos load, the reserve can get as low as 32C which is a bit scary but still safe when you consider that most normal applications will not stress the CPU that much even at 100% CPU load as reported by the Task Manager.  In the summer, the reserve is about 5C shorter due to the temperature difference inside my house.  What you need to make sure it that you seat cooler properly which is not easy to do the Core 2 Duo's socket layout.  I use Arctic Silver because it is cheap but I don't know if it makes a difference vs the stock paste.

Finally, to extend the life of the processor, I set my power scheme to laptop/portable so that EIST kicks in and the CPU multiplier is knocked down to 6X form 9X while the computer is idle or doing light duty like browsing the web or playing pacman :-) but immediately goes to full throttle when more processing power is required.  As a result, my 2.7GHz is running at 1.8GHz most of the time which happens to be the stock speed.

Good luck and let me know if you need help.

I am running the Rosewill Z-3 coolers I have 3 of these & they work great, the artic cooler you are looking at is fine.  But with the tags on it, it makes it a pain to install these coolers are not good for being used over & over.  That is why I like the rosewill or similar they use a back plate w/screws & nuts.  I am kicking around dumping my 6750 & going to the 6850 just for the extra performance.  I also prefer Gigabyte motherboards I have 3 of the GA-P35-DS3L, these boards are tough & great overclockers.
