NIGHT STALKER
There's a definite generation gap going on. The best way to speed up a Q700 is actually doing a 650 MoBo transplant . . . [}

Speed:
Yes 700 = 25 MHz, 650 = 33 MHz, but it's maybe 30-40% faster (just a feeling), OS is/are the same 7.5.3/7.5.5 don't remember now exactly. The OS on the 700 is also quite new, the 650 is loaded with some stuff, did way more with it than the 700. It's my 3rd use of 700, yet ever.
The HD indeed is only 160 MB in the 650 resides a 300++ maybe 500 but <1 GB. Does it make THAT difference? Would be Got a spare 500 MB ProDrive Apple OEM here. But this drive every half or minute makes a rattling sound, is this normal for this drives?
RAM:
So cannot mix, ok. But could I use same size modules of other size than 4 MB? I.e. f.e. 8 MB modules? 3x 8 MB = 24 MB or 4x 8 MB = 32 MB and so on...
Make it faster!
OC I have to dig around the forum a bit, I guess? Read about OC'ing some other Mac (was it 605?) by only changing resistors/soldered jumpers? Would be nice if same easy way to do on 700. Don't have an idea how hot it gets if OC'in by 133% 25 MHz -> 33 MHz. Now the heatsink without fan is estimated 35°C "cold" after 1h of usage.
Modern 10k I think is overkill 50 pin SCSI maxes out at 10 MB/s. Access time would be way faster and storage space much more of course. 10k drives often are loud. Didn't find a silent one yet.
Thx for info and
Regards

Modern SCSI Hard drives:
The 2.5" 10k drives i use are almost silent. - over kill? yes, @ 3 bucks a piece, who cares.
- thanks to james
OC:
you just change the oscillator.
HD:
Your right capacity really has no effect on performance.
Some of the older 160meg drives big and slooooow.
Ram:
I would install in groups of 4, and they all should match.
Speed:
Maybe run a benchmark, like Norton System info.
After its done you can see where your bottle neck is.
my bet is on the slow HD in the Q700.

Personally, I feel the performance differences between 68k macs are lost in the rounding error of 25 years of computing advances.
However, from a technical perspective, the 650 is going to have significantly better memory bandwidth, particularly with interleaving. The maximum RAM is much higher, and RAM for it is significantly cheaper. Add to it the fact that you can put the modified ROM in a 650/800 and get 520MB of maximum RAM, letting you have both a larger RAM disk than HDDs of the era with more RAM left over for application use than a q700 or stock 650/800, and I think I've found my favorite quadra.
There are of course other aspects to consider, such as form factor. I'm a fan of the 700's case, particularly over the cases of the 650 or 800. The onboard video of the 700 is capable of 24bit video where the 650/800 is only 16bit. The 650's SONIC ethernet controller is a bus master on the system bus, resulting in much lower CPU load for similar throughput. But for many practical uses, it's kind of hard to beat a several hundred megabyte RAM disk that is preserved across warm restarts, with hundreds of megs of RAM left over.

Q700, Greenish Tint Video. With adaptor set to VGA mode..
If your Pram battery is dead, Replace it, and if you are booting into a OS, 7.6 or higher, it will fix your greenish tint issue.
My issue was, i had 7.1 installed. and the pram battery was dead.
So i changed the PRAM battery. Booted to 8.1 from external zip disk. POP in the middle of the boot process it corrected the screen, (green tint issue). Rebooted and 7.1 now looks fine…
I think the Quadra 610 has this same green tint issue and Fix as well.

One of my friends that were into Desktop Publishing upgraded from a SE/30 to a Quadra 700 in early -92. Besides having color, he also bought the Apple Cd-rom. Still remember to this day the jaws dropping, when the Pc-guys with their 386s and Win 3.1 saw the setup.
One year later a few of the Pc guys had saved enough money to buy 486dx. But later that year my DTP friend upgraded to a Quadra 840a/v, and the PC vs Mac discussion was over.

i bought one, end 1991
the only computer powerful enough to handle 3D CAD,
auto-generate sections, 3D shapes with color and shadows
FPU integrated, lots of memory, AAUI,
slots for extra video card, CPU upgrade card
configuration (1991):
Quadra 700
RGB hi-res monitor
Apple Two-Page Monochrome Monitor
for backup : 650MB ram disk read/write at speed 1
mainly used for ArchiCAD v3 and Photoshop
plotter : Houston DMPL A0 penplotter ( not pictured )
later CPU upgrade
Apple Power Mac upgrade card
http://lowendmac.com/quadra/power-mac-upgrade-card.html
in use until 1996

One of my Frankenmacs is a Q700 motherboard in a IIvx case with a PPC 601 upgrade board. It was originally going to go into a IIci case but then I acquired the IIvx and liked the sturdy metal case that was capable of supporting a monitor on top better than the IIci case.

Ah so other wise you like the Quadra 700 case looks ?
Personally, Getting ready to do something crazy! (thanks MinerAI its all your fault)
I need to find a Q700 Case + Quadra 650 main board
then i am going to over clock it past 33mhz --->42?
And i'm going to load it up with 4 - (32mb) simms
Finish it off with a 10k 73gig SCA HD
if anyone has any of these parts i need let me know.
just tell me what you need for em. yellow or not n/p,
