Solved Why the runaround ????

Specs: Windows XP
I called a large computer service store to get ram, and I told him, that it has to be H/p brand of ram DDR2 SDRAM PC2 4200 (533MHz) and he said well ,anything will work. I told him that is what the specs manual of my H/p computer requiers and so I told him some specs and he said "Who told me that?" I replied "well those are configurations that my com. reqires from the specs, and he told me that it's all just a bunch of gobly gook,.
Here are my specs for my H/P Pent. 4 HT 3.GHz FSB speed 800 MHz
1 GB PC5300 (667MHz) (2 x 512 )
2GB " " " " (4x 512)

4GB PC4200 (533MHz) (4x 1 GB)
my cpu is single core, 2 threads, 3. GHz clock, L 2 cache, 15 bus/core ratio, 800MHz FSB speed, with a 64 bit instruction set, etc, etc,etc.
Why is someone saying to run 200MHz ram on this forum when that dont line up with my specs either???? hugh??? 200Mhz really makes sense to me , but why is it not specified then??? Why is HEWETT PACKARD telling me to run 533 MHz with 4 GIGS?? and not 200??
OH!! one more thing. How come experts on the net are saying that IBM and H/P USE THIER OWN RAM because of very strict specifications? and these so and sos' here in EDmonton are tellin me that it is not true?? Everyone is telling me something different. One store had H/P ram, but would not sell it to me!! they said that for 92 dollars they'll come over and install it.- not including the price of the ram!!! and they would not tell me the price of the ram!!!! ITS A SECRET!!! I am really upset now.

"I have 233gb of free space"

A 250GB HDD's actual capacity is not 250GB, it's approx 233GB, so it would seem there's nothing installed on the drive yet.

"All 250 GB models we tested have a real capacity of 232.89 GB (488,397,168 sectors). As you may be aware, the capacity advertised by hard disk drive manufacturers isn’t the real drive capacity. Read our Hard Disk Drives Capacity Limits tutorial for further information on this subject."

Is there a question somewhere?

Reads like a rant to me.

"Why is someone saying to run 200MHz ram on this forum". If you mean computing.net then how about a link.

Always pop back and let us know the outcome - thanks

Here's the link

OOPs wrong forum.......sorrybout that. anyway 533 MHZ still does not fit with anyones calculations that iv'e seen .right now Im runnig 1- 667MHz and 1- 800 MHzper channel (2 channel) and my coms working great. Its just that I want the right configuration. I'l just go with the specs.
the other link is the Ram link where I learned about H/P using their own Ram
Too bad I was not raving out LOTTO numbers.Kind of late for that now

Ok, first off HP does NOT make ram and they never have. They do not make motherboards, they do not make cpu`s, they do not make power supplies. Hp builds computers just like the rest of us. I am using a HP keyboard on an IBM computer? Back to your problem, the tech you spoke with is correct in that you can use any brand of ram. Your cpu runs at a 200 fsb and quad pumped equals 800 but your base speed is 200 x 15 = 3000Mhz. This is why people are telling you to use 200Mhz as your base speed, it matches your cpu speed. My experience with hp is there tech support is a joke.

Thank you very much, You have been a great help!!!! If I get the 200 MHz then my com will run better. Thanks again...I added another link where I saw the H/P ram thing.

Go to www.crucial.com and use their scanner. It will tell you what will run best on your system. You can purchase from them or to somewhere else.

Ya thanks fingers, I'ne already been there -done that quite a few times. They keep telling me pc2 5300 at 667 Mhz. . I like them. I got a widows xp pro 64bit o.s. commin in. should be here in about 17 days.

There's a lot of mis-information out there regarding which RAM should be run with which CPU. Unfortunately, the use of quad-pump & double-pump technologies have muddied the waters & made things a bit more difficult to understand. If you stick to using the frequency rather than the advertised/theoretical FSB & DDR speeds, it should make sense. To reduce the quad-pump FSB speed to the actual frequency, just divide by 4. To reduce the double-pump DDR memory speed to the actual frequency, just divide by 2. Then you can compare "apples to apples".

Generally, the CPU & RAM should be run at the same base frequency. This is known as having a 1:1 CPU:RAM frequency ratio. For the majority of Intel based systems (P1, P2, P3, Core 2 Duo), a 1:1 ratio will give best overall performance. However, the Pentium 4 (& it's derivatives) are highly inefficient, in fact, the P4 is said to be the worst CPU to come out of Intel. Anyhow, to help make up for the P4's inefficiency, it's best to run the RAM at a higher frequency than the CPU. There are two CPU:RAM frequency ratios that are considered optimal for a P4 configuration - 3:4 (for 400MHz FSB or 800MHz FSB CPUs) or 4:5 (for 533MHz FSB CPUs).

Since you have an 800MHz FSB P4 (which uses quad-pump technology), the base frequency is 800/4 = 200MHz. And since 3:4 ratio is considered optimal for an 800MHz FSB (200MHz freq) CPU, the RAM should run at 200MHz X 4/3 = 266.66MHz. Which RAM runs at 266MHz frequency? DDR-533 <-- there's your answer.

You may like XP, and for a P4 CPU it probably is the optimal OS (except maybe Linux), but the 64bit version was never fully adopted by many and cross compatibility was the worst from what i have heard. Also make sure that there are XP/64 bit drivers available for it. Also, there are very few programs that are for XP that can take full advantage of a 64bit environment. I am not even sure that 64bit Photoshop fully supports xp in 64bit if I am remembering something I read correctly and Photoshop IS one of those programs that really do work better under a 64bit (typically under Windows 7) environment. I am not saying you should go with Windows 7 with that machine (wait until you get something more modern first), just that I do not think that 64 bit XP will give you any advantage and probably more head aches.

Yes, Fingers, I kind of heard that also. I heard that Windows brought out their 32 bit version because it was alot more user friendly. When it comes in, I'm not goin to try install it right away. I will wait until I know enough about it and what I'm doing .
I was being an idiot and accidently deleted an important file and my com would not load, telling me that it could not load because of this.
I ended up having to reinstall because I was lost in the black screen dos type commands of the repair system. Any way, it told me that if I install on a different partition,then all my c files would not be wiped out so I did that and all my files got wiped out SO IT SEEMS. I did not see it deleting or rewritting anything. This same situation happend to me last year and I reinstalled on the SAME partition. I saw windows deleting files and overwriting the os already on there. Well, my Tech 5 music program was still there,although I lost my Command&Conquer, and all my icons and pictures. Only the Tech 5 disk can open the program file.
Coud it be that my orig. os is still there but I cannot see it? I did an analysis with my defragmenter but only saw the new stuff. I also watched a full virus scan but only saw the new stuff.
Someday I will get a new machine but for now I figure that I'll get a brand new hard drive nice and clean, load up the xp/pro64 and start all over. Someone once said that "If it aint broke,and you mess with it long enough,........it will be" This is what happend to me.

I hear you... I have often used an old hard drive for a destination when installed as a second hard drive (after OS is loaded and running). I typically take the hard drive from the old machine, install it as a second drive, transfer all old files I want, format the drive, and make it a destination for my back ups, that way they are on two completely different hard drives but always there. I also typically keep a copy of all program installers that I do not have install disks for in a folder that gets backed up too. In your case, when you install the new OS on a new hard drive, make it the only drive plugged in (it then gets a complete boot file) and when it is running and when you have everything installed and you are sure you like it, you can then reinstall the original hard drive. you can make a complete drive image to it (reimage it periodically) so if you ever get the itch to 'mess with it' again, you can always restore it from the image.

Thanks for the advice Fingers, on the drive that's in my com right now, it is a 250 gb.- I upgraded from 80gb. Anyway, after reinstalling the o.s. on a different partition, The analysis tells me that I have 233gb of free space so If I find out how much space only one 32bit o.s. uses, I'll know for sure if there is something else on there.
