bad mem benches?

[fireball_87]

sorry about the messed colors, had to save it in 256 color format lol.

Is that the 8KHA+?!? That would look a bit low. BTW, why haven't you been on AIM lately?

[SteveI]

Is that your new XP???? @ 150FSB!!!!?????
Absolutely unacceptable! Check your settings, any DDR board should be doing much better than that at 150FSB.

[proze]

those are indeed low benchies. what mem timings are you using? still, i don't think changing from cas2.5 to cas2 or anything like that is going to increase your benchies THAT much.

what version of sandra are you using? get the most recent release, as afaik the older ones had issues with xps and mem bandwidth.

Fireball_87: Try Sandra Pro! It has been fixed to work with the XP.
Here is a shot of what mine looks like. Hope that helps. Jim

[EPoX Tech]

Sandra Professional edition is known to be bugged with memory bandwidth scores - this result I attach proves such between both (memmory scores taken on 8K7A with XP1800+ at default speed with optimized defaults loaded in BIOS)

[EPoX Tech]

and the professional (quite obviously false and flawed) edition. Sandra Pro is not fixed to work with the XP, but is broken from the start.

[dimmreaper]

Fireball, looks like you need to play with some BIOS setting to me.

[fireball_87]

this is my new xp 8kah+, 150fsb normal mem timeings, cas 2.5, pc 2700 ocz ddr. im gona try playing with some bios tweeks, but this relly has me stumped. i coult acheve this with my old kt7-raid lol

ps: im using the standerd ver and win 98se for compairson resons (part II of xp review)......

[dimmreaper]

Well that's your problem!

Put the memory to turbo, set it to CAS2, and be sure 4-way memory interleave is enabled.

[fireball_87]

ok, here it is. timings: fast, 4 bank interleve, cas2. win 98 dosent like anything above that. cant wight to try with 2000/xp im cureently at the almost dangros level of 2.9v ddr. in a week or to im gona try some ram sinks, and my fop32/aopper cak38 on the northbridge. i think i need to unlock it to hit 166. i know this chip's got 1.6 or 1.7 ghz in it, but im to chiken to do the voltage mod for now

[dimmreaper]

2.9V ain't dangerous. I run 3.0V all the time, and have run 3.2V for hours on end.

That memory is real crap ya got there, hope you didn't pay a lot for it(no offence intended of course, I just think maybe you have been had). I can run at those speeds with a mere 2.7V with my Crucial memory.

My advise: Go for the Turbo settings, 4-way interleave, CAS2, and however much voltage it takes. If it takes more than 3.0V, consider heat spreads, but go ahead and run without them until you get 'em.

ill give it a try i paid $55 for it and only got it because it was supposeldy "pc2700"

[EPoX Tech]

Real quality PC2700 will do 200MHz easily in a SiS 645 board.

Epox Tech : Not to disagree with you but there is a update for Sandra Pro! The new Ver. # is 1.11.8.53 not the Ver. # 1.7.8.20 that you are using. From what the site says and what i have read on other sites. It seems that they have fixed the bugs they had with XP and the new chipsets. I still feel that all of the Bencmarks are only to check changes on the system it's on. There is no way to compare other systems as they are all set up Diff. Some people do test with clean installs and people like me do test as the system is used on a daily basis. I want to see what changes do for my normal setup not for a bare system as i don't work on a bare system. Hope that helps. Jim

[EPoX Tech]

The benchmarks are flawed - they show benchmarks inflated by in excess of 100% on i845, KT266, AMD761, AMD762, KT266a and Pro266.

This is patently obvious. Gaining performance by running a bugged benchmark is no gain at all !!!

I can guarantee you that the figures reported are incorrect in your screenshot. Everyone in the hardware website world uses the smaller correct figures - take a look at all of the benches on such sites as [H]ardOCP or Toms Hardware - they all use the smaller figures. particularly take a look at Toms comparisson of all the latest processors where he does a memory benchmark.

What should highlight to you the fact that it is a faux is the fact that DDR beats RDRAM PC800 on the P4 for bandwidth which is quite patently impossible !!

All day today I've been doing real world benching rather than just concentrating on memory bandwidth by doing the ZDNet office and photoshop benches along side some gaming benches. Going back to Synthetic benching I had some good gains in 3DMark2001 just by tweaking the FSB and BIOS.

[ZX1100]

Epox Tech : As before I am not about to disagree with you . But the Sandra Pro Ver. # 1.118.53 will only give these higher scores. So what im saying is compare these #s from the same Ver. on the same system and who cares if they are high or low. They are only my #s from my system set up the way i use it! Who is to say if any of these benchmarks are right? They can be made to show what ever the programer wants! So as i said before i just use them to check changes i make to my personal systems! As such i don't care if they are high or low, i just need to see if the change made any diff. I will keep my info to my self and not bother you or any one else on the group. Sorry if it created a problem for you. Jim

I'm surprised, My Crucial cas2.5 DDRs are running stock voltage (2.5) @146.6FSB fastest timings across the board. Are you sure the memory is unstable w/ less voltage?

[dimmreaper]

Oh and Fireball, if extra voltage won't make the memory go faster, try manually setting the DRAM Drive Strength settings to there maximums. This sends a stronger "tic" to the memory modual.

[fireball_87]

ok, got it up to turbo at 3.1v lol. im sure it isint stable at lesser voltages, cus win98 eather gives bsod or reg errors.

ps: thanks dimm, ill try that
pps:the northbridge seems to be getting awfal hot. as soon as i can get my hands on some thermal epoxy ill mount my fop 32-1
