UBCD is wonderful!
Here are some suggestions for making it even more wonderful:

Whenever I test RAM, I want to check the L1/L2 cache details/performance (some older computers cannot fully cache RAM past 64MB). I use CTCM16N, MEMSPD, and CACHECHK. These are simple DOS programs from the late 1990's. It would be great if they were included with UBCD, or some other programs that do similar things.

They could be grouped together, and even autochain:
>MEMSPD -d -qq
>CACHECHK -d -qq

It is too bad they won't check the cache timing past 64MB -- it would be great if someone would come up with something improved!

This utility from c't magazine displays CPU info (type, step, model, speed, etc) and tests cache performance.

(This is the version I've been using, but a more recent version exists I think.)

MEMSPD will do memory accesses to check out the cache (L1 and L2), and RAM, telling you the speeds and sizes of each. It's the cousin of CACHECHK, with the goal of fully loading the memory access sub-system, to drive 100% utilization of the memory bandwidth, regardless of CPU speed.

CACHECHK will do memory accesses to check out the L1 and L2 cache, tell
you the speeds and sizes of each, and check to see if all of your memory
is cached, or if some is non-cached.

Let me know if you need help trying to arrange permission or whatever.

It would be good to have something to pull out as much RAM SPD info as possible. DIMM_ID is a simple DOS program that can do some of that. It would be good to also have something that can get as much of this info as SiSoft Sandra.

Another thing I'd love to have on UBCD would be something to show the actual CPU clock, multiplier, the RAM clock, and all the memory timings. It seems like H.Oda!'s WCPUID is very popular, but requires Windows. But he also offers XCPUID for linux, so maybe there would be a way to include this in UBCD?

Thanks! I will include the DOS stuff in the next release of UBCD.

I will also try to get Adrian to add XCPUID to his boot disk (currently contains CPU Burn-in, StressCPU and MPrime).

I'd love to take a look at xcpuid, but the linux version seems to be for "Members only".
Anybody got the linux version?

Please try this:

and tell us all what you learn!

Also, does anyone know if any of CPU-Z can be used in pure DOS -- esp the cache latency special test!

I was reviewing this for UBCD V3.5. I have added DIMM_ID, but I think I will pass on CTCM16N, MEMSPD and CACHCHK, since they appear to be rather dated.

Adrian, any luck with XCPUID?
